Originally I had the idea to lock the grate on top and you would have to climb a variety of ledges to climb out and unlock the grate. That was a little too ambitious for a 72hr game jam so we just went for the legs and arms.
We totally should have locked the root on the wrist! Great catch! Didn't even think of doing that.
The legs and arms were actually going to be fullbody IK. Obviously, we didn't have enough time for that otherwise that would have been a cool way to increase immersion and you would have definitely noticed your legs were locked. If we can restore the game after I messed up the github we might get a chance to update it.
A skip would be a good idea too. We figured there were a lot of games to play so we didn't go for replayability. There were some ideas thrown around about procedurally generating the key locations or dropping the keys from the top of the grate into the well using physics for variety. Thanks for playing!
