Wow...
This is great! Really fun game man! This has a lot of potential for a bigger game and I have a few suggestions:
A risk reward system (the closer to the crash the car is moved more points?)
A skill system (with said points, or pay at the end of the level?) you could buy upgrades (time slow, cars could have a chance to revive after a crash, magnet so cars can go close to your cursor when you are clicking?)
That's all I got, Keep working hard and making good content my dude!
PS: if you have any games on another platform pls tel me your Dev name or your or game names.
Edit: I was gonna put this as a review, but I forgot to add text there, I gave it 5 stairs.
