I really enjoyed this little arcade game! Simple formula that feels good and replayable. The grid movement felt nice (I appreciated being able to hold a movement button to continue moving), and the art and title screen are charming.
I found the title screen text a bit difficult to read, and I think it would be nice if the cannons appeared a moment before they shot, acting a cue for the player - or some other creative cue! I also had a bit of trouble telling which hearts were filled and which were empty in my health bar.
Great work, I'd enjoy a version with some of the missing features included!
