Not bad, but...
Maybe I didn't pay enough attention, but, I was unaware that the white things were enemies and not power shots. Still, nice though.
Good game, one flaw.
I liked it, especially the way you have to use the small orbs to get rid of the larger ones, looked pretty cool to combine several into a web around you.
The only flaw with this game was a bug I found: If you pick up more then the required amount of yellow orbs (in this case 21 out of a required 20) you fail the level and have to restart, which I assume wasn't the intention.
Great game however.
