    Excellent game, one of the better I've played on mobile. Only two complaints: no indication on the map which levels have unlock images, sometimes when drawing short roads pressing the button to start a bridge had it jump in some random direction forcing a restart. An undo would be nice and maybe more indication of how you can improve an intersection. Cheers. Full Review

    I'm not a great fan of the retro look, but it's a solid concept and plays well. My big hang-up is the lack of an undo button. Playing on a phone makes it all the more necessary for me to undo mistakes (which happens often.) It begins to get frustrating restarting for the tenth time just because I screwed up one road.

    Love it. Finished it in a week. There is no delete road button, and that's part of he charm of this game. You screw up, you restart the level. At first, I didn't like it, but now after finishing all the levels, I absolutely love it. I recommended this to my dad and he sits there playing it when he is not playing some games from the era of Windows 95, so it seems to get his approval too :) Full Review

    For the most part the game is great but it's held down by one major flaw. No erase or undo button. I've got bigger fingers so I was constantly making mistakes in my road building that required me to restart a whole level. The game felt more monotonous than fun because all it was was me redoing the same pattern over and over because I had made a small mistake which caused the road to not connect properly, making all the cars slow down, failing the level.

    I looked at the blueprints and my stomach tensed up. "This can't be right?" I thought. The flat stretch of pavement we set was already drying, there was no "undo" for this. "This was supposed to be elevated!" I screamed to no one. No matter. On my authorization the westbound lane would have to cross here either in a traffic circle or a multi-million dollar bridge. I took my pen and amended the plans hoping I wouldn't lose my job and that traffic around here would finally move smoothly. Full Review

    This is a perfect game for me, as a kid I would doodle roads and intersections. Only problem is, no undo button. Even I had an eraser as a kid! But I'm really excited for it and hope the dev keeps on with the game that's so close to awesome! Full Review

    A beautiful simple game with 1 major flaw. I don't think I'm the only one here stating it. You build up your road network and then test it. If something is wrong you can either add to it or delete everything. Made all the more annoying when it could be a small error in your plan. I am wandering why there could be no into button but if the answer is to extend game play why we have paid for the game already. Full Review

    In concept this game is quite fun, after seeing the Nerd3 video on it, I instantly went and found it, discovering it on android as well as Pc. At this present time however, I wish I had bought the PC version instead. It has a couple flaws which turn the game to frustration. Mainly there is no undo or erase button, which is a major issue when a certain bug occurs where you take your finger off the phone to build a new road, but no matter where you press, it continues from the last place. You end up with weird road placements and then have to delete the level and start over. Full Review

    I enjoy the game. It needs an undo button and/or an erase function. Understanding how levels are evaluated would be nice, as would knowing the budget. No level has the concrete to simulate large interchanges near where I live, such as where 95, 495, 395, 644, 95/395 Express Lanes and 495 Express Lanes interchange in five levels and 28 ramps.

    Half baked. I expect quality for a paid app. Controls are Garbage. No snapping ability. No undo button. Almost unplayable. Great concept, this app feels like a garbage beta test than anything else Full Review

    I want to love this game so badly. I just cannot get over the controls. For God's sake, add an undo button. Also better snapping to other road nodes would be nice, as well as some grid snapping. Full Review

    I really regret my purchase. I watched a video online that made this game seem much more intuitive and seem like the controls were actually functional. I can't get the roads to snap, it doesn't start construction at my fingertip at times, no methods to delete roads, no undo, and no input as to what makes roads successful. Unfortunately this game falls apart after the unique concept. Full Review

    Could not get the Android bar to go away. It covered some of the street starts so I couldn't play the game. I have a Moto so usually I don't have that bar. Only had this problem in this app. Before the bar appeared I loved the game. Full Review

    This is the traffic flow simulator that I've always dreamed of. Some other reviews have commented on the lack of undo button being an issue, but I think that's a feature; we get the freeways we deserve, not the ones we want. Full Review

    I understand, this is supposed to be a simple time sink. For the love of god add an eareser or at the very least an undo button. Very unfriendly to the limitations involved with using a mobile phone which takes it from entertaining to unplayable. Full Review

    The game is fun but held back by lack of an undo or erase. If you make one error you're only option is to start over again. I'd gladly rate higher if this feature was added Full Review

    It's a neat concept for a game but there's a few flaws. Controls are imprecise, and lack options like erase and undo. It'd also be nice to be able to change elevations BEFORE putting down inital roading. There are some bugs too. On-ramps that are placed too close to bridges sometimes interact oddly. The cars will block cross traffic even though they're on different elevations. The game also doesn't like running in the background. When I've come back to it after switching to another app, it'll often just be a black screen. Sometimes half the screen is stuck in the portrait orientation. Overall enjoyable for a few hours, but expect to be frustrated by some of the problems I've mentioned above. 3/5 Full Review

    I love everything about this game except for the lack of an undo botton. A otherwise elegant game constantly interrupted by the need to erase an entire area due to one slip of the finger. This turns an interesting logic game into one of ridiculous and unnecessary precision. Full Review

    Addictive fun, but there's some flaws that make playing frustrating. For starters drawing lines on a smartphone is difficult to do precisely, so a mistake or glitch in drawing means starting a level over. Really need an undo button or eraser. The biggest flaw in my opinion though is that you have limited concrete, but it doesn't say anywhere how much is left. You just run out at some point, usually right before your design is finished. Time to start the level over again. And finally nothing indicates how busy a street is going to be before you connect it. You might think connecting two highways is priority, but then for some reason hundreds of cars poor out of a neighborhood instead. Full Review

    It's a good game that is crippled by the inability to erase roads, or at least undo the last move. This issue makes the game almost unplayable on mobile. Full Review

    In short, the game is a great idea bogged down by glaring mistakes. The biggest issue by far is the lack of an undo button. Sometimes, roads don't work like you want them to. In that case, you have to clear the entire map and start again instead of just undoing that one bad road. And, with the touch screen tracking not that great in my personal opinion, it makes this lack of a feature even more frustrating. This game is an absolutely wonderful idea, and a great puzzle game. It just needs to be more user-friendly, and it'll be one of the better games on the store for its price. Full Review

    This is a great puzzle game turned moderately sour by several small problems. There is no undo or erase, and combined with the slightly erratic and unintuitive control makes it easy to ruin a solution and be forced to restart. Some concepts aren't shown, like the concrete limit (which I didn't know existed until a later level, and which this game absolutely does not need), how exactly your score is calculated, or that some connections have varying levels of traffic. Once, a solution that was obviously about to jam passed in a very unsatisfying way. It's also sometimes hard to see all of the connections between endpoints because my finger gets in the way, and a button to see all of them at once would be nice. Overall, however, the game is fun and addicting despite those flaws. The game is almost worth the $3 pricetag. Full Review

    What could be a great game ruined by REALLY crappy controls (builds roads when you touch another part of the screen sometimes but there is no indication of whether you are laying it or not as yellow icon frequently disappears, no way to erase roads, no budget and no idea how much concrete we have left. Can't see roads under bridges so groundwork frequently destroyed when said icon vanishes...) Put it this way- Q: How much concrete is there? A: Sorry, we can't tell you that. Q: UM, why? You asked us to build you roads...we need a budget, or at least some kind of ballpark figure? The machines are really old and dont work well...please? A: No. We are Ash-hole.Inc. Ok boys, lets go find another employer. Let us know if you improve your business strategy but in the mean time? Build your own damned roads. Full Review

    I want to like this game. But, as many others have already said here, there is one fatal flaw that makes this game virtually unplayable. That is the lack of an erase or back button. I would be less annoyed by this fact if the game was free or even $1, but the cry that it is $4 makes this omission totally unacceptable. I will gladly rate this game 5 stars if the problem is fixed, but until then, 1 star. Wouldn't purchase again. Full Review
