This is truly a rolling ball game.
I'm afraid that the ball keeps shrinking randomly on restart sometimes.
Are there any gameplay differences between the characters? I'm also interested as to what the story could be. I suggest adding a skip dialog button because unskipabble story sequences are generally a bad match for arcadey games.
Another suggestion is that it would be cool to have a 3D preview of the level ahead of time.
I'm still too bad to beat most of the stages, and I think they lack an escalating feeling of challenge in general which they should probably have considering the length.
I like the UI a lot. It looks very SEGA.
Keep up the good work.
