Fantastic game! One of the best I've seen so far in this jam. Was originally drawn to it by the art style and because it looked similar to "Into the Breach," but it's more reminiscent of those Connect-3 type games. Everything about this is awesome from the art style, to the title screen, to the sound design. Everything works smoothly and without bugs. About the only thing I could ask for is maybe more clarity as to the building types, and possibly a type that will also remove corruption to add elements of strategy for extended play.
Otherwise, hats off to the devs. Good luck in the competition. I'd be surprised if this game doesn't place.
