Cool game, the player character is very weird (in a good way!) and carrying a tower defense chain along your back is a novel idea. I like the audio design of effects going off and starting to stack together as you get more things on your back and zooping around clusters of enemies feels good. When in the gameplay loop, pushing buttons feels good and the camera swooping in to a close up of the tail pieces is a lovely bit of polish.
The biggest thing I think working against this game is its lack of movement restrictions, oddly enough. You’re able to dash very quickly, nullifying pretty much any attack by the enemies, and since you aren’t constrained to stay in one place, you can keep dashing forever in one direction and go further and further into space. It seems like when you do that, any enemies that spawned behind you will just get left behind forever and new ones won’t appear. Some kind of level boundary, or even a point where you wrap around to the other side, would help prevent players from literally getting lost in space.
