It's an auto tetris game, it's not bad, but you dont really do anything. What you see on the first machine is all you get, when you buy the 5th machine the UI breaks down in a scrolling manner so you can see all machines, even tought you cant really interact with any of the past machines.

Each machine have a limited amount of upgrades and maxing it is pretty fast/easy, the AI is overpowered from the start, in a way this is a good prototype, but for an actual game some heavy balancing and more features are needed or else the game-play wont last past the first machine.
