This is a small patch including jumping buffer for both normal and wall jumps and a fix for the map screen, where pressing 'return' on the keyboard caused the game to quit.
What does jumping buffer means?
It's very simple, up until now for jumping to work you had to be on the ground or near a wall, now you get a few extra frames of buffers for any jump request, so if you hit the button slightly before you hit the ground or the wall, the jump will still register.
