Yeah, you are right about how little the game conveys its mechanics. Sadly, I joined to the jam later, which explains the state of the game, but it doesn't make it any better. For the most part it was "do I implement X, while the core elements aren't even in place" and as a consequence I had to cut corners. Well, the time after the jam is to polish a game and I'd like to see how much I can squeeze out of the premise.
