This game is VERY active, you essentially open a series of doors, each of which has a new multiplier in the form of a new mini-game. It's a clickfest as you're juggling between these games, but the last few doors break it open to more simple prestiges and automation, and it's fun to hit the end when you're off to the races and blast open the final door. Not a game to run in the background, this is one if you wanna plow through a short, single-session experience. I liked it for that purpose, though.
