This is an excellent little puzzle game. Challenging, truly demanding of thought and logic, and very interesting and unique.
The presentation itself is nothing special, it's simple, but it doesn't have to be very flashy, after all, the meat of this game is in the gameplay.
The gameplay involves tile sliding, and the objective is to push "fan" tiles off screen. For that, there are different kinds of controllable sliding blocks, that you will more often than not see yourself having to push around in intrincate ways to get to the goal. There are the basic horizontal and vertical blocks, and to beat the stage, you sometimes have to push horizontal blocks using vertical blocks and vice versa, and sometimes you even need to make intrincate pushing schemes where one block pushes another which pushes the fan. The levels are challenging right from the start, but not unfairly so.
I really like this, I must say.
