I may consider the idea to purchase this game but i don't know there are some active players

tell me things you would like to see in the game and if this gets popular enough the creator may notice

So i just started playing this game again (i quit originally because no matter what i did, eventually i ran into this problem making it impossible to play) but im on puzzle 4 and im trying to move the bottom right board rook to the bottom right of bottom right board, but no matter where i move the rook it becomes a yellow square and the only option is to undo turn, and this, to my knowledge, is never explained and the game just tells you you're wrong without actually explaining why you're wrong...

Hey, i just bought this game but when i click to launch it it opens a window for 1 second and then it just closes again Am using Windows 10 please respond if you need further information

The following game seems to have no legal moves as white, but the game is not marked as checkmate and I had to forfeit after half an hour of trying to find a legal move. Can someone help? https://imgur.com/a/KPfqzoL
