Nice stealth game!
A couple of things I liked: it was pretty handy to be able to see the whole vector of movement of the enemies as they start to move, it feels pretty fair giving you time to react, and another cool feature was the idea of sneaking underground on the small doors, I think it could be used a bit more as you could beat the game without needing them.
Also a small detail but there's a little bug where you can still lose after beating a level, but it should be a matter of stopping the enemies when you beat it.
Pretty solid for a game jam scope, good job!
