This game is a cool take on the theme, and I think it works well exploring how sometimes doing bad things can lead to worse things, once you stop caring about being bad? All I know is that I became an amoral killer faster then I'd like to admit.
I think the stairs need a rework, in a game with a timer they're too unreliable and I found myself wasting time jumping around them. And it would be good to have optional paths to some switches/keys. I had one switch that I think I was supposed to be the bat for, but I managed to get with the spider instead!
