NES Demake Pixel Art Animations

I’m building a faithful Nintendo NES demake of Blasphemous and need help finishing two key art assets while respecting every hardware quirk of the console.

What I need you to do
• Animate the Penitent in seven states: standing, walking, ducking, jumping, climbing, getting hit, and attacking.
• Draw the background tile set for the Warden of the Silent Horror (static for now).

Technical boundaries
– NES authenticity is my top priority.
– Each sprite must stick to exactly 4 colours, transparency included, per 8×8 tile.
– Please follow the look and mood of the original Blasphemous game, distilled into classic NES form.

Deliverables
1. Clean PNG sprite sheets for every animation, separated by frame.
2. A PNG tile sheet for the Warden background.
3. A text or image reference of the exact palettes used for each sheet.
4. Files tested to load correctly in NESFab (colour-compatible with its assembler).

Hand-off is complete when I can drop the sheets into my NESFab project and see them render without colour conflicts. If you’ve shipped art for other NES-style games, feel free to share; otherwise a quick mock-up showing you understand the palette limit will move things forward fast.
