very cool almost roguelike game. I did find that it feels a bit to easy to lose your spray almost to the point that if I miss more than 2 times I'm pretty much done for since the drops to replenish wasn't that much. Perhaps playing in favor of the player I would add logic that makes the drops lean more towards whatever the player is missing more. For example, a few times I got like 3 hearts dropped and only 2 spray refills when I was in full health and only had like one pixel left of the spray. I think a change like that could help extend the play which can be a fun arcade like experience if it wasn't so easy to run out of ammo.
