Game Night!: This weekend! https://www.facebook.com/events/317792721696252/
Awesome hand drawn graphics and animation, coupled with some really great music and sound design. The puzzles were very challenging, but usually were not too obscure that you couldn't figure it out (and for the one's that were, there is a nice little guide build into the game, if you so choose to use it). It's short, but I really enjoyed it while it lasted.
