This is a super neat idea! I do wish I felt like I had a little more control of stuff (maybe have a swap tile, like in tetris, or maybe choose who goes to heaven and who goes to hell?) and maybe a few more interesting tiles (some of them were pretty cool, but I also felt like there were way too many neutral guys), but I really enjoyed it as a proof of concept. Graphics and writing were also pretty neat.
Apart from the level music having a much lower volume, it also seems like the menu music is panned pretty far to the left? A little annoying for headphone users.
Anyway, all in all, very solid entry!
