Kimi K3 Powers a More Complete Game Demo
chongdashu · x · 2026-07-17
Building on a previous Paper Mario-style demo, the creator refined it using Kimi K3 and Grok Build:
- Added cel shading and outline effects for a more stylized 3D look.
- Introduced an NPC that follows the player.
- Incorporated sound effects and music, noting that audio is essential for the full experience.
The quoted post details the previous workflow: Kimi K3 was used with Grok Build as a harness, enabling the model to invoke agent skills and tools to auto-generate 2D/3D assets. Beyond using Spriterrific for 2D assets and geometry for 3D assets, it autonomously handled implicit details like:
- Making trees semi-transparent when blocking the player.
- Creating a card flip animation.
The author plans further testing but is highly satisfied with the current results.
