Whoa...
Dude.. awesome game... i'm addicted!!! Great physics, the challenge level went up a tad slow, but can't be helped.
I was having fun easily shooting off the floating drones and, to my dismay, i discover that suddenly want to follow me Xx not to mention they explode when they hit you...
you should try adding actual other stick people in to shoot at (throw in more than just training)... although, if there are people, i apologize, i'm only so far in the game... Ooo... try throwing in scrollable stages (kinda like madness or that other game i can't remember right now that reminds me of madness)
i suggest either more starting ammo, or be able to pick it up from the drones (or people, if you decide to throw them in)
this game has great potential... i want to see more
