That was awesome. I didn't realize what was happening with the map until I opened it for the first time at the last expansion, and my mind was blown. It would be cool if there was some sort of animation when you got to the key goal 3/3 and it showed the map expand. Navigating to that 12th key was super cool. There were some inconsistencies with map where it looked like things didn't connect even though they did. The ending was a super cool effect, but I'm a bit disappointed it didn't lead to a satisfying conclusion.
Super awesome game
