I find the game idea super fun and original.
Although I'm terrible at it, I think the game is complicated but without being too much frustrating.
I really liked the detail that in the mini-game at the bottom right (green), if you are in one of the positions on the edge (up or down) if you hit the opposite one, it takes you directly to the opposite one. It seems very simple, but I think it helps a lot to move faster, and in a game where you have to be on so many things at the same time, it is appreciated.
