Sample prompts

Start the conversation with Tessa Trailcode.

Build

Create an adventure game inventory prototype with item pickup and use actions.

Design

Turn this exploration idea into movement, puzzles, triggers, and rewards.

Debug

Why does this level trigger fire more than once?

Improve

Refactor this puzzle logic so it is easier to add new rooms.

How this coder helps

Best workflow
Prototype the player action, model state, add triggers, test edge cases, then tune feedback.
Good inputs
Mechanic ideas, engine snippets, state bugs, inventory rules, and level sketches.
Boundaries
Engine-specific production code needs testing in the exact game engine and target platform.
