Sprite of main hero and second one after power-up.
Also mugshots of scientist and robot girl.
4 colors for each one.
Everything looks fantastic except for the last character sprite on the right. The arms are too long and the pose is awkward.
Hey, can you please use a non-resized preview? We like to have previews as pixel art as well. Also, as the preview is over 10 kB, this doesn't show up on the front page.
