Hi Shnurbs, I was able to finish levels 1 to 3,and got stuck at 4 and 6 :(
I have no idea how to hit the green long-range ones using the body of the red melee ones; I can't jump up to them, and they keep hitting me from above :(
The new body I got at 6 seems to warp me around, leading to my having to restart the game a few times :o
