It's a cool concept but it's quite hard to play and hurts my wrist a lot. There's just way too much going on, too much added at once, and I can't keep up with it at all. I don't know why I lose a run or not.
I feel like the positions of the little dudes should be reset back to their origins once a new round starts. There should also be less dudes added during a round, since there's 3 new ones each color and that makes it really, really tough.
I also ran into a glitch where I died with the grab-all powerup and it was permanent no matter what I did.
Overall, it's alright, it could be better, though.
