No hard feelings, critisism is always welcome. Speaking of bats, they only kill player if they are not carrying any bones, otherwise it's a bit like sonic and rings, you lose some of carried bones which you can pickup later. You could also jump on top to get rid of them (and get some extra bones). Otherwise yeah, bumping into them is part of the challenge, I guess, sorry if you found it annoying.
Yeah sounds are on a quiet end, wanted to add sound settings at some point but rapidly ran out of time so I just leveled every sound to be somewhat on a same volume level.
Thanks for playing and commenting!
