You will die

As a blue cube you must platform your way through many deadly obstacles whilst making sure to reach the end. This is a very difficult game. It involves many tight gaps and little checkpoints. There is no saving, no hitbox kindness, and in future possibly even more frustrating features. The game is not completed hence the reason it is not free. Most likely on realease to the public the price will drop to 0. Good luck, because you will die.
