Can offer pixel art skills: characters, monsters, effects, avatars, mascots, objects, idle stance animations - but in quantities not fit for games.
Single character pose - $19; 2 poses for the same character - $34; 3 poses for the same character - $40.
If you need different characters they'll be $19 each.
Effects: Animation - $45
I can probably manage a single mockup, but definitely not the game projects. Have only around 10 working hours per week.
Top-down roguelike mockup: Price based on $25/hour wage. Mentioned example took 8 hours.
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)
