Thank you so much for the comment! Which screen resolution do you have and which build did you download? I unfortunately didn't have the time to make a proper settings menu, that's why I went with the easiest approach possible...
If your screen size was smaller than 1920x1080 I know why it didn't work, if that is not the case I would love to get a bit more information on your running conditions to fix this :)
I knew about the getting stuck in the ground thing. But I still to this day have no idea why it is happening haha...
Edit: I just tested the game on my linux laptop and noticed that the bug that causes the player to get stuck happens way way more often there then when I originally tested it. I believe it is because of the way I implemented frame independancy. I think I didn't account for deltatime in the ground check or something!
