Sorry about that -I just tested it and the button worked for me -mind if I ask what browser you were using? Any other details might help too -like was it on a touch screen?
That's weird, idk if you fixed anything but the reset button definitely works on that level when I'm not out of moves... haven't tested getting stuck again
Edit: so it happened on the LAST level this time, a crate floated back up after the move but it won't let me move there. When I hover over the reset button, sometimes it goes purple and sometimes it doesn't, but clicking doesn't work
Edit 2: I scrolled back up and clicked it again and it did work this time?? I'm very confused
