Can offer pixel art skills: characters, monsters, effects, avatars, mascots, objects, idle stance animations - but in quantities not fit for games.
Characters: 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.
Avatars: $15
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...
