Several cubes of different colors set off on a journey to get colored crystals for their world. They will not tell you why they need stones, but apparently they are. Once the blocks are ready to risk their own lives for this. Initially, at the hero's level, it is located on a small island filled with crystals. They need to be collected, but you cannot go through the same place twice. Following the cube, the road disappears and there is nowhere to return. If you make a mistake and send the block to the wrong place, click on the button in the upper left corner and the level will start over. Use the arrows or ASDW keys to control. Each section on a new level will be more difficult than the previous one, before moving the block, think about what this or that step will lead to.
