Hey, thanks for the information!
I knew about the first and the third bug, the first one has to do with my player doing the ground check incorrectly, I will try to fix it. The third bug likely has something to do with the fact that this is a browser game, just click the screen a couple of times and the game will return to normal.
I am interested in what that second bug is, can you possibly post a picture?
Thanks already and hope you enjoyed!
