It's a fun game but there are a couple of issues, bugs are a problem that happens once in a while, I wish they would add a delete tool and not just an undo button, and the biggest thing is that there are only 2 worlds, for what you pay for there should be more as it only took me a week to finish the game with stars on every level. but overall a very fun game

The game is pretty fun all things considered and I'm really glad about the undo button (seriously, thank you for adding it), but I can't help but feel like the car-AI needs an overhaul. They sometimes refuse to take the fastest/shortest/most direct route for no apparent reason, in some levels roundabouts somehow end up working worse with direct right turns outside of it than without (which doesn't make any sense since cars turning right wouldn't even enter the roundabout to jam it up)

On the one hand, the idea is a lot of fun and can definitely lead to many hours of play. On the other hand, the game doesn't always recognize when roads are connected, sometimes it doesn't place the road where your finger is, and worst of all, there's no "undo" feature, so a heck of a lot of those "many hours of play" consist of starting the current screen over from scratch.

What’s new

A whole new 80 level map awaits!
Concrete on the map is cheaper and more plentiful, but traffic is worse! Luckily we've invented toll booths to earn some extra efficiency points.

And at long last, Undo technology has been invented!

And finally, your best scoring designs will be saved while you work on potential improvements. You can restore your highest scoring design at any time.
