So far this is one of the cooler concepts I've seen. It's only really bogged down by the fact that its unfinished. Would be very cool to see the finished project. Another point to add, and this is not so much a game development related critique but a game jam related one - most players really will only spend 5 to 10 minutes on an jam game, so setting the objective to require 15 minutes of gameplay means most players will not finish or get to see your whole game
