Ohh that's just mean. Nice challenging level. I especially like what you have done with the horizontal stairs and fence, esthetically.
Spoiler: Central part Autowalk/Claustrofobia trick Spoiler: Solution Tapparo on brown block where is B
Spoiler "My mistake, the beginning I tried to throw B. and then B accidentally thrown into the box wins. "]
Spoiler: The End The final ball isn't useless. Imagine which mechanism it may active Spoiler: Another Hint Why this level has this title? Spoiler: Final Hint What's the purpose of 2° ball?
Spoiler: Clarification You must active the central mechanism. It seems impossible. But there is another way to reach the win(No skills).
