Most may find the puzzle game too difficult, but you do not have to complete the whole level.

The game throws you into the fire without teaching you the rules gradually. There is not even a proper tutorial, just a few images showing the mechanics. Essentially, this is a Sokoban puzzle in which you have to push round lights into slots. However, this is never easy because you have to pay attention to the layout, which does not allow for much moving space, gaps that must be filled with boxes, and so on.

To be fair, you do not have to activate all of the lights to accomplish a level. It is enough to get at least 60-70% to go to the next level, but if you want the achievements and all the stars, you will need to complete every light.

There are 100 stages. To break the monotony, there are a few special stages where you have to reach two stars by controlling two lights at the same time.
