OMG its amazing!! Its probably one of the most interesting games I played.

It reminds me of the marble labyrinth maze (maybe this name) I played when I was a kid!! 

I like the game that it looks simple to play but actually hard to control!  And nice job of the level design! I can tell every level is well designed and arranged. The rotation function suits the game so well! 
Also sound effects are nice, I like the hit sound when small ball hits the wall.

Really nice game!! XD

A superb result!

I totally second this comment ^.  One tiny thing I would change, maybe you should make it a little bit more forgiving hole-wise. Other than that,  a GREAT entry. The visuals were super solid as well, you have a great sense of aesthetics. 

Very well made! If you polish it more and put on Steam I probably will buy it!
