Thanks for playing, I'm happy you enjoyed! I saw this bug happen once on someone else's machine, and I could never reproduce it. I was kind of baffled to be honest. Do you have any idea what you did to make this happen?
i swear i just moved the big block like you are supposed to and one or more pieces of it just stay there. Maybe it could have something to do with the undo mechanic i think i remember undoing before moving but i wouldn't be able to tell for sure
