One piece of feedback that I got about my homebrew game Robo-Ninja Climbis that the main player sprite is a bit drab. Which is pretty true -- graphics are generally a weak point for me. I was wondering if any of you talented folks here had any specific suggestions or advice for improvement. The sprite is based on a character that I've used in an Android game and a NES version of the same game. Attached is a screenshot of what he looks like on the Atari game, and in the NES game. I have enough kernel time to add color, although in my own attempts at graphics, I haven't found any colors that I feel like make it look better.
So that said, if anyone is interested in helping me out, I'd appreciate any ideas or advice y'all have.
Just a couple notes: I've decided to go with a black background to prevent the HMOVE lines from being visible, which is why I inverted the character's colors on the Atari. There's also a couple other animation frames (jumping and rocket), but I can adapt those based on the main sprite. I don't feel like flickering him, so I don't want to do something crazy with two sprites at higher resolution. Th exact height of the character isn't set in stone, but I'd want to leave it approximately the same size.
