Really fun, I enjoyed it a lot! I liked how frenetic it got, I think it could even do with a more stringent time limit.
I think that what would improve the game a lot is tweaking the crossbow to shoot more in line with the player's crosshair and to have clearer boundaries for the bomb explosion, as well as making it more obvious when the player is hurt.
That said it's a really fun prototype. Good job :)
