100% Local free experiment: Agent + Model + GAME ENGINE - Need Tips & Tricks

I'm curious about trying something I want to test which supposed to run 100% locally, Free, Offline using my PC Specs limits: Before I made this post I did a small test and it was very impressive for what it is and it made me wondering if I can push the limits to something better with control for complex project. I simply loaded LMStudio (because I'm a visual person) and I've tested: Qwen3.5 35B A3B Q4_K_M - (probably there are newer / better versions up to date) I tried simple classic game-clones: Snake, Tetris, Arkanoid, Space Shooter, etc.
