Such high praise! We are humbled and thank you :)
Into the Breach was the direct inspiration for the art and its pretty cool that it shows!
We had plans to add in a way to combat the corruption but ran out of time to implement it so it will have to wait till a commercial release unfortunately.
I plan to make an update post jam to help clarify what each tile is as we've been seeing the same confusion from many players, thanks for bringing it to our attention!
