Can offer pixel art skills: characters, monsters, effects, avatars, mascots, objects, idle stance animations - but in quantities not fit for games.
I can probably manage a single mockup, but definitely not the game projects. Have only around 10 working hours per week.
Limitations: character height - under 120 pixels, if it doesn't imply animation. And under 60 if it does.
Mockups: not bigger than 360x240.
I'm bad with old specific palettes, like cga or commodore 64.
PS: I can draw anime characters too. (Not pixels)
