Using a bouncing NPC to convert the outside edge of the grid is a really cool mechanic. I see lots of potential for implementing a really interesting puzzle game based on it. However, without a losing condition (some kind of countdown timer or other mechanics within the grid that'd lead to losing) your game feels more like a technical demo than a game, but I think it's really awesome that you submitted your game in its current state, even if it's unfinished—I wish more folks would do that instead of giving up. Based on what I've seen so far, I don't think you're far from making something really special. I'd be curious to check it out again if you continue to developing it. Thanks for making and submitting your game!
