Very fun game and a unique take on the genre! It's like some chaotic combination of wario's woods and puzzle bobble. I loved the sound design too.
My only real gripe was that aiming with WASD felt a bit awkward at first since I was already using the mouse for vacuuming. I would have preferred to be able to use the mouse to aim, though it didn't take me too long to adjust. I think being able to fast forward the drops a bit would be fun too, just to speed up some of the early stages for replays, but otherwise I really enjoyed this one. Good job!
