Learn how to use Unity MCP with Claude Code to rapidly add polish and "juice" to your 3D platformer prototype. In this second part, we explore using AI agents to implement a platformer blob shadow, squash and stretch animations, a custom gradient skybox shader, add simple UI using Ui Toolkit, collectible coins, a respawn system for falling off platforms, and a "win star" to restart the game loop. We also tackle triggering dust particles and sound effects through animation events, while fixing logic bugs like the "phantom footstep" loop using a minSpeed gate.
