Hey, thanks for playing the game! Totally agree with what you're saying. We have a new build coming out on the 10th with a lot more enemies and traps, auto-repair, some more levels and a bunch of balancing updates that should make it a lot more fun.
I think long term we might want to add some unlocks and whatnot, but that's for later. Thanks for checking it out! Would love to see you come back and give it a go next month :)
