For how simplistic this game is, it's very fun and hectic. Absolutely rock solid arcade gameplay, but I do wish there were more powerups and that they appeared a bit more often.
Graphics are also really nice! I love all the little attentions to detail like how the smiley face has animations for losing some goofuses to the Vortex and gaining health, or that the vortex changes color when it absorbs some dudes. The music appears to be bugged for me, but I didn't really mind.
Overall a fantastic game!
