Build a small 3D game level with real Blender doing the 3D work: write Python scripts, run Blender headless, export GLB, then make it playable in three.js on one web page. The game is Small Hours: at 3:07 a.m. a kitchen-table inventor shrinks herself to 4 cm with her own ray, so the kitchen is 40x real size (she is 1.65 m tall, the counter top is at 36 m). In Blender, build by script at 40x: the counter with a sink, a chrome toaster, sugar cubes, a wooden spoon, a mug on its side, a window with moonlight and an open fridge glowing warm. Model the heroine and a house cat (about 18 m long) as low-poly characters, rig them and animate them in code (hero: idle, run, jump; cat: walk and pounce). Export one GLB under 60k triangles. In three.js: third-person WASD, Space to jump, mouse to aim. Left click grows and right click shrinks the object under the crosshair, so sugar cubes become steps and the spoon becomes a bridge over the sink. Each shot costs 25 charge and the ray recharges only in light (moonlight, fridge glow). The cat wanders and chases her when she gets close. Show a HUD with charge and the triangle count of the loaded GLB. It should feel magical the moment it loads.
