I'm on ubuntu 16.04 and i use xfce, I was able to fix the issue by rebooting my pc and reinstalling the game, have only had the issue two times since the first time I've commented and rebooting my pc fixes it everytime without the need of a reinstall. This game is a really fun demake, cars don't work but the character basically super jumps so it's not a problem lol. Thanks for replying, nice to see that you're willing to help people unlike other comment sections I've seen on here.
Glad you found a solution to this problem !
Thanks ! I've been thinking about correcting the game and finishing it, especially car physics (which is horrible). When I'll have more time I think I'll work on that.
No problem. I'm always happy to help. I want everyone to play my games in the best conditions.
