I like that game, the concept is fun. The game was pretty difficult with all these cars, I wasn't able to finish every level, but I believe that was a way to counter the buggy car's pathfinding.
The controls felt pretty great, nice chill music.
Some things you can improve about coins :
- The Coin Collect SFX was getting a bit annoying after some time. You should randomize the pitch so it gives more variety to it.
- The blinking coins idea was good because I almost couldn't see the coins when they were white especially in the first level, but I think you could have made the coins already yellow/orange/gold and the blink would just change the color a little bit (yellow -> orange mabye) as a polish element (could even be 1 coin per one).
Good job... also, thanks you for the playtesting !
