It's a very unique game and impressive for making 2d in unreal. However the goal was at first very unclear but i believe that the roads are randomly generated and  you have to choose how often cars spawn on the road. But since i got a good road I managed to progress a while without changing anything. I was mostly confused and when cars eventually crashed I was even more confused since I didn't realise what had happened. A very original game but too confusing.

The cars would crash at different spots even with no variables changed. Idk what is causing this, but between this and the fact that the game doesn't show where the crash happened unless I happen to be looking at the intersection when it happens means that I would occasionally "solve" the puzzle without knowing what I did or even not doing anything different at all.

With these things fixed and a lot of fleshing out artwork and sound-wise, I think I would enjoy this game a lot. It is fun to build complexity incrementally when it works and see the whole thing moving smoothly. There's something satisfying here, but not yet.
