Game runs amazingly on Linux under proton. Love it so far.
About 35 puzzles in now as of this comment.
I was thinking, perhaps and addition of "pen" tools or some sort of marking beyond middle click? Making notes I can only middle click on empty tiles, but would love to be able to mark over current ones.
Something i can make notes for my math as I'm trying to figure out some of the overlaps. Might be a worth while addition.
Solid game, feels exactly how a UFO50 style game would be.
