Hello! This has the makings of a super cool game. I think my son would enjoy it very much too. I have two suggestions:
1) When you die, it would be cool if it restarted you at your previous spawn point rather than randomly generating a new level each time. As it is, it's difficult to learn from mistakes because everything is in shadow and it's different on every attempt.
2) I think it would really pop with some mysterious, almost somber music.....something I very much enjoy producing! I'd love to do some collaborating with you if you are interested.
