It's fun but here's my feedback:
The first bullets are so slow
The second is you can just hold the LMB forever, I liked the idea of collectibles crashing when they collide with bullets, you can expand on it and you can add a little bit cooldown to gun.
That's really all liked it, btw please check out mine :D
yeah I've been updating the game to where shooting the hearts will hurt the player. About the bullets. Did you try using the sliders on top left? It's a key mechanic of the game and allows the player to adjust the bullet speed and the rotation speed. It was so that the player could make different bullet hell patterns to play the game.
