On wave 12 the enemies just stopped coming, might be a bug. Otherwise, it was a fun tower defense game. The game feel is a bit lacking and the selecting and upgrading of the controls is a bit awkward.
Thank you so much for playing and for the feedback! Aw man that's annoying that the game still will stop after a few rounds-- it has to do with the pump jack enemy and the logic behind us spawning it and moving it off the path.
