I finally got around to cleaning up that body-piece tile. It's still small but I've cut out all the duplicated rows and columns, so it looks much better.
Not only does it look cleaner, it also overlays perfectly on the largest copies of the body tile on Awesome Level. So now someone just needs to produce a nice 2x version of it.
Also, between your rip, the Lemmings level, and screenshots from the Atari ST version* of Awesome, I've managed to piece together a good copy of the head sprite.
(* I couldn't get the Amiga one working, but the graphics of that guy seem to be pretty much the same between the two - only the colors changed, and I edited my work to match the palette of your Amiga sprite.)
I should probably note that the top two rows of pixels did not show up in the screenshots I was getting, nor do they appear in the Lemmings level, but I put them in 'cause you had them in the Amiga rip.
Anyone know for sure what that dark bit over the eyes is supposed to be? Is it perhaps a reflection of the player's ship?
