The game is fun and that's about it. Swinging around is really well done, the movement is fine, and the music/sfx brings me back to good old 2016 Roblox.
The swinging is so fun, but I feel like the enemies and weapon don't compliment it too well, you could fix this by maybe making the purple enemies fire projectiles instead of teleport (which was really frustrating), and/or making the gun use hitscans instead of slow projectiles.
The glitch theming is fine, I think you could have done more but it's fine, however, I feel like the game somewhat failed to fit the "planet" theme, since there isn't any mention or showing of the planet outside of the itch.io description.
