Such a cool game! I think a weaker entry would have omitted the wall jump, but that wall jump so beautifully ties this game together and makes it an incredibly enjoyable time! An amazing concept that worked brilliantly, as every step I made had such a strong feeling of risk to it which is an exhilarating gameplay experience.
I think if you just added the right music and sound effects to this to really make the atmosphere shine, it would be absolutely perfect!
