Cool game,
I really like the art and the narrative.
The enemies spawning in SFX is a bit repetitive I'd say and they often get stuck on objects, I also noticed that their speed was changing sometimes, not sure if that was intended or not.
The idea is very nice, the riddles are cool.
I think with some polish and lighting this would make for a nice puzzle game.
Would be nice, if there was a way to deal with the enemies other than switching scenes maybe.
Nice entry, Good job!
