This is a bullet hell SHMUP. Left stick moves, R button shoots, L button uses a screen-clearing bomb if you have one, and the A button shoots a laser when your meter is filled. You have a health bar, and even when you lose a life, you just get a line of text saying how many lives you have left and your character just keeps moving forward (instead of the usual “explode and immediately fly back on screen”).

Not much to say about this one; it’s only three levels long, and the levels themselves don’t overstay their welcome, either (I beat the whole game without losing all my lives). As is typical for bullet hells, your hitbox is much smaller than your character sprite, though actually taking damage results in a simple pop sound effect, so there were times I wasn’t sure if I actually avoided damage or not. It has a decent variety of enemies and bullet patterns, though in level 2, the player character and even a few enemies tend to blend into the background if you aren’t looking directly at them. Also, while most bosses tend to stay by the bottom and let you shoot at them from the top, the level 2 boss has a near-death attack where it’ll suddenly bolt to the corners of the screen, including the top ones (naturally giving you no time to react nor to move out of the way since it’s way faster than your character can move). The level 3 boss (the final boss) does something similar where its tentacles will shoot into the screen from the horizontal edges, later gaining the ability to bolt upward/downward after stabbing and shooting their volley.

Maybe worth a playthrough if you got that 1700+ itch io bundle, but I don’t think I’d recommend getting it on its own. I did have some fun with it, but its short length, visibility issues and cheap hits make it tough to recommend even at its cheap price.

EDIT: Oh yeah, the game starts with this weird lighting effect where the corners are dark and the middle has a yellow transparent circle, but you can turn that off in the options and play the game normally.
