I plan to wait a bit before I rate this game, to see if the dev makes any changes. I've played to completion, I've played many games like it; that's not a bad thing, what's bad is that there many other games like it that I'd rather play first at the moment. It has promise though, and I'm hopeful that a few balance changes and a clean up will make it one of the best games in the jam, albeit a lacking in the theme a fair bit.
Edit: I have now played the game after it was updated, I like the improvements, and I can now say that this is not last game of its kind I would rather play. Having been able to enjoy it more, I can better feel how it connects the jam's theme. I still wish there were some more changes made to balancing and level design, but for what it is, it's a great game.
