Managed to recover this one so better share it before it's gone. Just some (chubby) astronaut. The sprite size is 16×24 and it takes up 10 tiles for 3 frames of animation. Use first frame for idle, all frames for running (1-2-1-3 order), second frame for jumping/falling. I may make more frames in the future, but these are the base ones I guess.
Sprites themselves:
Tiles making up the sprites (using palette colors 0 to 3 in the PNG, if some tool needs that):
Placing this in the public domain if anybody wants to use it.
EDIT: now that I look again at it there seems to be a mistake in the legs in the second frame... (the legs are supposed to share the same tiles in the second and third frames)
