Has a really good feel to it. You absolutely to managed to make the glitches and bugs fun. They add to the atmosphere while not really taking anything away from it. Really well executed.
At some point I managed to move at the bottom of a platform by repeatedly jumping against it. That was a really cool glitch as well but seemingly an unintended one. xD
The simple art style also worked surprisingly well. Well done, well done. Great result. :)
