Very fun game, nicely done. The main suggestion I would have if you decide to do more jams would be to focus on one or two main mechanics that set your game apart, especially in large jams like this you will usually only a few minutes to get the players attention, so having a couple really polished mechanics the player gets to see is a better management of your time than more unpolished mechanics the player might skip past. Regardless, I really enjoyed the game, its impressive what you were able to put together in 7 days!
