It gets better
I thought this was a good game because you were drawn in to play it longer. Now, there is really not much detail with just a blank background so I did not like that part. I do not know why, but I still enjoyed it even though there was little detail all throughout. I thought maybe I was going to learn something about particles, but I guess I didn't. Well, maybe I was supposed to recognize their patterns or something. What's interesting about a game like this is that you can choose to either go all around or stay in one place until a ball gets near.
The best way for me to play it was to move away from the balls. The good part is that some of the times they pump into each other so they lump together and there is a wider area to avoid them. The sound effects were nearly spot-on with a game of pool. This was a fun little game to play it was just not elaborate. That can of course work because you avoid superfluous stuff.
