I love that this is one of those games that if you wanted to, you could play with another player and it would be a good social experience. The dual objectives that pulled you in different directions was a bit mind-bendy in a good way. The pulling on the chain is an interesting limitation and I wish a bit more was done with that (though I understand it is a game jam :P )
And the art. Wow! Everything from the UI to characters is great!
All in all, great job!
