This is a great little game that is remarkably well made. Without spoiling anything, the mechanics that the game relies are implemented fantastically and run smoothly and without issue from what I've seen, which is not an easy feat given the time frame.
A good number of the games submitted to the jam feel like prototypes, as is the nature of Game Jams, but this games feels like all it's missing is some possible graphic polish and more content and it could easily be a game worthy of being sold.
