I really like the art. It's a weird mix of styles, most of it is very nice but that inconsistency and a silly overture to it makes it work for SBIG Jam. It's sometimes hard to tell where the hitboxes are on enemies because of how they rotate, but that's probably a feature here. The sounds are very silly, but work perfectly here. I don't think I'd call the sound design excessive, though.
The gameplay I'd call functional but not standout. It's a hybrid shooter/tower defence and it's... fine? The balancing and progression are pretty unpolished- at the end I'd built a turret on every platform and had tons of gold. The enemies are all damage sponges and the weapons aren't terribly satisfying. But it only goes on for ten rounds, and none of the issues are so egregious that they kill the game.
