Ah man!, when I first saw the main menu, I though that you used the graves as buttons, turns out not :/, though I highly Advice to try to do it, it’ll be much cooler like that
The game idea is good, I liked the differences between the realms, but the wall jumping wasn’t consistent, sometimes the skeleton will jump up and sometimes the opposite direction, and it was a bit annoying to wait for the souls to come to you in order to gain you soul to be able to transform, maybe you can make them start slowly moving towards you once your soul isn’t full just like a magnet
The last area I reached was very dark, I couldn’t play properly so I quit, but good game overall, good job
