I got this a long time ago, but only tried it now. Apparently an update changed how the game was, but I cant comment on that.

As it is right now it feels less like a shooter and more like a platformer where you jump from one grenade (purple orb) to another keeping the swarm somewhat at bay and collecting points. And you try to do it as long as possible until you screw up the flow bad enough.

I cant really seen any patterns, any strategic or tactical gameplay, I cant even tell if Im going to be hit or not.
I wanted to get 10k to get all of the achievements and see if maybe Im missing something, but no.
Its not that its that bad considering its price and as a sort of platforming experience it might be alright, but as a shooter its pretty unsatisfying.
