Thanks a lot! I didn´t know about GetAxisRaw but i´ll use it next time. Do you mean with "stuck in the wall" that when the wall is right and you go to the right it´s kind of in the wall? Because i have no idea how to fix that.
About the squash and stretch thing: I didn´t have time to make any animations but i´ll definetly use some pixel art and walking animations next time. :)
