Fun game! Was kind of confusing, but I really enjoy the spin on the theme. I think it was the only tower defence game I saw on the jam, which is also pretty good. I feel it may've bugged on me? At some point I found it really hard to assign towers to my keys. I feel having a checkbox to make it work like it is now or to automatically assign itself to next key on the list, when a tower is placed could help with that and general gameplay flow. All in all, very nice game with great idea for itself. Good job!
