This is really fun. Adding different abilities to the tower might make it feel less like a cookie clicker game.

I love the idea of an only-one-tower TD game, but it definitely needs more possible upgrades to optimize. Additionally, it felt like the rate enemies kept coming was impossible to keep up with. Still, I thought it was a cool idea. Good job on your first jam! Oh, and the music is great.

The game is enjoyable but  there isnt much room for strategy with only 2 upgrades.

I like the music!
