Ok, so, about this level, this is pretty much a showcase of really cool bug which I discovered like 20 days ago (honestly, I don't know if it was found before or not, and this is exactly the reason why I decided to create full level just so it wouldn't be very lame). BUT, this bug has some downsides: random noise (I tried to hide it as much as I could), lags and strange behavior. Also, I'm not really proud about level itself. I feel like it's too unstable. If you don't want to get through all this trouble and only want to see this bug just watch video above (you can see it at 2:54 mark).
Spoiler With beginer's luck I solved it quickly, without having to fall down . But when I retried it, unable to repeat what I did before, I was able to make good use of the ball only to get stuck there. Then with the video I realized how you fooled me Bravo, well crafted level
