Plan A Simple Level For A Game Engine Beginner

You have opened the engine, placed a few cubes, and have no idea what to build next or in what order. This lays out a realistic first level, small enough to finish, with a build order that avoids the classic beginner trap of lighting a level that is not built yet.

<context>
You are learning {GAME_ENGINE} and want to build one small level to practise, rather than an entire game. You have built [a flat test room with a few cubes] so far.

**Plan a first proper level:**
1. Choose a level type that teaches core skills without needing advanced systems (a short obstacle corridor, a single puzzle room, or similar)
2. List the concrete building blocks needed: geometry, lighting, one interactive element, an exit condition
3. Break the build into an order that avoids common beginner traps, like lighting everything before geometry is finished
4. Suggest one stretch goal only if the core level is finished early

- A numbered build order, five to eight steps
- One paragraph on what to deliberately leave out for this first attempt
