Very fun! I love the mechanic and it's a great way to combine the theme and limitation :3 if you'll allow me a couple suggestions, I think it would be fun if the projectile kept damaging enemies even after it hits the first one, so one could plan more strategically to hit multiple enemies with the same shot. Also if you wanted to make the game more fast paced you could introduce a mechanic for the projectile to "attract" the player when you press a certain button so it's a bit faster to retrieve the projectile while still keeping the chaotic element of having to go retrieve it to the other side of the screen. Great job overall <3<3
