It's awesome once you finally understand it.
This is one hell of a puzzle game! I mean, sure, the learning curve is pretty advanced, but once you understand how to play, it becomes so much fun.
Let me see if I can explain it a little more clearly to those players who are still confused. You start the game with a bunch of sticks with round heads. One of them will start moving when you hit play. It will then continuously travel in a clockwise or counterclockwise direction on a square path. The square path's size can be changed to one of three pre-given sizes. When a moving stickhead hits another stickhead, the former will transfer all of its energy of motion to the latter.
Your first goal should be to get one of the stickheads to pass directly through the blue square marked 1. When you do, blue square number 2 will appear. You must then figure out how to get a stickhead to pass through square number 2 while still hitting square number 1 as you already are. Once you do that, then you will have to figure out how to hit 1, then 2, then 3, and the process continues from there. If you're lucky, you'll reveal several steps at once. You win the game when you reveal and pass through all 34 checkpoints. It's that simple. Of course, it's easier said than done.
But anyway, this was one helluva game. I got a great mental workout from it. Sure it's not the flashiest game, but it's one of the most stimulating. A 5/5 for you, my good man.
