Really interesting concept. Although there are some stuff I don't really understand. I triggered a power up, and a few seconds after the power up ended, I won out of no where. Anyways, really addicting game and one of my favourites as of yet.
It's so addicting, I had the urge to play it again! Also, what makes the game end? Is it an hidden timer?
I would really want to see a Human VS Human version, or a version where you have to fill 90% of the game, or even a full game with additional stuff,. But maybe that's just me.
