There's some cool mechanics! I liked the knockback gun a lot, although the force could probably be reduced? Movement felt very floaty which made it a bit difficult, but I still managed to beat all the levels. You could consider adding more level mechanics, similar to the rotating platforms in the dropper level! A larger variety of mechanics would give a lot of potential for different uses of the guns which would really enhance the gameplay. The story was definitely engaging and I liked the effects and the twist of one of the levels becoming upside-down? Very cool stuff, great job!
