Hi! Tysm for checking out my game! It’s amazing to me that people are still finding it all these years later lol.
My sister actually encountered a bug once playing this were she also couldn’t move any blocks in that room? I never did figure why it happened, but I bet you got the same bug? Refreshing the page and continuing from her last save fixed it for her though, so I’d recommend trying that!
If you still have troubles with the puzzle working after refreshing the page, please let me know!
