honestly, extremely good for something that isnt the final verison on the game. Every mechanic is clearly communicated to the player via simply playing the game, which I think is really smart and makes the process of actually going for a high score really easy and fun. Only real feedback I had was potentially communicate the enemy health a bit better, maybe through a health bar that only appears when you damage them with either your projectile or a bomb. Personally I think that would make the rapid-fire decision gameplay that this game has a bit more interesting, as you would be aware of which enemies you'd want to prioritize, and overall just have more awareness.
