There are only two feelings you feel in this game.
1:"Oh, shit, that's not a gap, is it? Oh, sweet, it is!"
2:"Oh, shit, that's not a gap, is it? Nope. Not a gap."
Fantastic game!! Just about the only thing that, I think, would make it better, is if you had something like a dashed line projecting the first little bit of the balls path, so you could aim a little better.
Why did it take me until the first level of the hard pack to figure out that hitting spacebar pauses the freaking game?!?! So many times I could used that!
The only thing this game needs is a simple, good ol' fashioned proximity alarm. Not even anything as fancy as radar, just something that says "Look out, you're about to hit something!"
