Task: Figure out a way to pass through the levels, break the bubble on yourself, and return to freedom.
The operation of keyboard ↑↓←→ is very simple. Pay attention to using the mechanisms!
PS: All the menus in the game are quite interesting, set by foreigners, and they sound pretty stiff. Here are some of the most awkward translations:
Hard = Very difficult, Go back = Return to the previous level, More points = Score, The following level = Next level...
