The main purpose of this level is to test and manufacture two organs. The end block is hidden in the organ, it will appear when the right ball is pushed. Low ceiling & SBS is needed Spoiler: Hint There are two stars for hinting the hidden structure, one star is the standing position, and the other is the click position when doing SBS. Spoiler: Video
Surprising, fun mechanisms! And nice use of stars to direct the player. But I thought the moves by the lowest stars were too obscure and hidden...
Cropped and scanned. It worked. As you openly declared the tricks and said its a test level. So I don't think it required any rating. And.. You forget to mention Herclue Push by Springboard Stair which was quite hidden to perform, Cancel Pop to avoid Clastrophobia and Long Run Stair Jump Level would have looked more clear & beautiful without Water. Game was lengthy, where as I liked your R and Win surprises.
So sad ... had it all figured out but impossible to do that springboard stair there by the lowest star ...perhaps as I'm on a newer version. Awesome level and loved the sensor causing a friend to appear when B needed help!
