This is a very simple and addictive puzzle game. In order to get to the next level, you need to find all the crystals and close the portals.

The game is similar to a platform game. You have to move through the levels and find all the crystals. Each level will have two or four gates, which you need to close. The gates will allow you to move to the next level.

The game has two worlds: light and dark. The evil from the dark world is trying to get into the light world through the gates. You need to find all the crystals and close the gates.
