First let me say that the techno music in the beginning was some of the best game music I have heard.
The gameplay itself is also impressive. The very foundations you laid in the past can come back to hurt you in the future, making every decision by the player have huge consequences. The only minor nitpick is that there's an "easy" strategy where you just stay close to the ground and collect 1 coin at a time, and I feel like this strategy breaks the spirit of the game. Maybe it's possible to not have coins so close to the ground?
Overall it's a very simple but nearly flawless game in my opinion.
