Why does it go like that?
This was a decent attempt at a game but the main flaw is that you just have no control over the ball. It always leans to the side no matter what you do. I guess that's what makes it challenging, but it can still be frustrating. I should have read the author comments because I thought those black things led to a portal or something. It's not a bad game because it does have most of what makes a game good. It's fairly original, even though there is not much detail.
Next time, try to put some music to it or sound effects. That is always a plus when dealing with submission of any kind. The artwork that is shown is actually pretty good for what it is. I guess I just like to see the little ball move as it jumps through the air. It's the little things like that that do not make it terrible.
