The game is entertaining, I played until round 30, the gameplay is kept simple, fast and challenging.
I think it has a lot of potential, thinking outside of a jam, if more things are added like an upgrade system for example.
I got stuck in round 38 because I didn't have more space to place towers :c
Yeah, that was something I didn't think about until after people played it. No "Start Round" button means it's easy to lock the game. So... in this version of the game, you won!
