You guys nailed it!
Closure is a beautifully unique idea.
For a game that could have easily been sloppy it had a tight feel to it. You are dealing with single pixels for credible jumping and movement so to have the engine recognize and work with that is fantastic.
It's a very chic game and with it rolling after Aether I am continually being surprised by your ability to go above and beyond. Keep it up.
Additionally, nice job Jon. You did a great job breathing life into this game with subtle but exceptional black and white artwork.
