So nice to hear!
I assumed, “Windows” would be kinda easy? (At least if you don’t want to max out your highscore.) What made it hard?
I think not knowing what the exact conditions are to complete a round made it hard, I had to corral the two guys into a corner and use the four available blocks to lock them in diagonally, but because the area I was trying to get them in was so small I really struggled to keep them both in the corner long enough to block them off-- maybe I'm missing something!
