The red square found itself in a multi-level maze of platforms called Jump Drop Shell. He wants to get out of the trap, but he will have to go through all the levels, and they are becoming more and more difficult. However, the hero has an ace in his pocket, namely his ability to leave his shell, becoming smaller in size. But this allows the block to jump higher and get to the right places, and ultimately to the portal, which will lead to a new level. If the hero knows how to jump out, leaving a shell, he can also return to it or pick up shells at levels, but they must match the size. A very small square will not be able to fit into a large shell in the Jump Drop Shell.
