This is a draft featuring about 60% of my latest project (8 phases). Arrow keys to move, A and D to aim your bullets (green bullets automatically target enemy), hold S to slow down. For practice, you can use the space key to set the boss's health to 1, thus triggering the next phase. The black dot in the middle of the green square is your hitbox. If that touches a bullet, you lose 1 hp and gain some invincibility frames. You start with 8 hp, and if you reach 0 hp, you lose.
well, ive had a knack for making scratch bullet hells...
