This is such a cool game concept. Tower defense games have become so formulaic so it's nice to see someone trying to freshen up the genre with a little creativity.
A bug that I found to be a bit annoying was that if I went to place a structure, and the tiles tilted before I placed it, I would have to go and reselect it before I could actually place the building down. It ended up being a bit frustrating given the cyclopes consistent tilting making it difficult to rebalance on the fly. Minor bugs aside, I had a ton of fun playing this game, and it feels like a concept that could be expanded after the jam into a full fledged game.
