Thank you for enjoying my game!
This game definitely changed a lot during development lol. Originally it was going to be a top-down survivors game where you defend a vault that could also be upgraded to fight back. The original idea I had was a lot more "tower-defense" themed and I am definitely going to spend a few weeks adding the things I had planned. (And untangling the mess of code written at the end :)
Have fun with the other submissions!
