Nice work! Great concept, would love to see it fleshed out more with some enemy variety, I didn't feel the need to mix up my strategy at all. Also gamepad/keyboard support for the menus would be nice, I can easily see playing this on the couch.
Thanks for playing! Id definitely like to add controller support to a game like this. As for enemies, yeah, I ran out of time, I wish I managed to get a few more tho.
