I cant move the boulder... tried so many times. Collected the gem.. sometimes it moved a bit, if i jumped into the boulder at just the right time but there was no control. Shame looks good.
Thanks for playing! That's so strange I've never hit and issue with controlling the boulder at all. Just to double check you're on the level with the green gem and once you've collected the gem and a new boulder spawns you can move it with the arrow keys?
If so can I ask if you're on pc or Mac? I'd love to try recreate this and get a fix sorted!
