Things I liked, i did like how you had it balanced where you would only need health when you took damage, and I think its very easy to tell that you spent a lot of time working on the sprites and they honestly look pretty good.
Things I didn't like, wasn't really a rewind mechanic in the game, kinda defeats the point of the jam. also even the I was getting new weapons constantly, I didn't really feel like I wanted any of them as the bazooka felt like the best weapon.
