I can jump up the wall and if I touch a wall it stops me from moving further upwards. There was some art clipping around the doors too, but I loved the artwork! The music was nice but some sound effects I think would of added something to it too.
The only other thing I wish I had better control over was the camera when looking left or wanting to look where I was falling for example!
Good job on the game though it was a nice play! I got through a few of the areas and got the heart thing in one of the later rooms!
