Overall, I absolutely loved this! The core loop is so fun that this could easily be expanded into a full, standalone game. A few thoughts on where you could build on this awesome foundation: The enemy action is super fast and intense! Giving the player a subtle warning indicator before enemy attacks and adding a bit more distance/spawn margin around the base would make dodging feel even more rewarding and reactive. We could have more defensive tools etc. The pumpkin catapult is such a fun mechanic! Adding a few additional weapon types or unlockable levels down the road would make the gameplay loop shine even brighter. I would also felt that camera was moving a bit slower at points of the game so that could also have like a sensitivity option.
Amazing job for a jam submission you’ve got a fantastic base here!
