I tried it on pc and I was able to grab the key just fine, I'm really sorry about that. Are you still having the same issue?
Yes, it's still not working. I noticed when I hover over the sheep, it turns green and the "space bar" button pops up over it. If I hit the space bar, Nigel can move the sheep a tiny bit, but not much. When he hovers over the key, it doesn't change color, but the "space bar" button does pop up. If I hit the space bar, there's a metallic "tap" sound, but the key doesn't move at all, and when Nigel moves, the key stays where it was. I'm running Windows 10.
