Retro car racing minigame (WIP) (Patreon)

This weekend I've tried remaking something like one of the first games I've played, with a bit more flexibility of course. However, I've bumped into the usual frame rate problem with timers before time ran out.

It is playable, but don't expect that much from it for now. Next weekend I'll have to refactor the code and use sprites to fix the choppy animation before adding collusion and the rest of the game.
the code is in the attachments, give it a try and let me know what you think
