I really like this. I’m currently making my own retro-racing top down game, and so I am always looking at other similar games.
Yours is very fun. I played on Android, and it was really easy to play. The obstacles etc are great fun.
I did find the screen zooming a bit jarring, but other than that, you have a great game there that will only get better with the more options you add like extra tracks.
I really, really liked it.
