Hi everyone,

Together with u/baruchgeuze we are sharing **StackTower**, built for the Lenslist Spectacles Community Challenge. It’s a precision block-stacker game;

The core highlight is the **real-time multiplayer**; in the demo video, we’re playing a synchronized session between **the Netherlands and (Bali) Indonesia**.

**Features**

* **Low-Latency Multiplayer:** Built to handle high-precision stacking across massive distances.
* **Physics-Based Slicing:** Overhangs are sliced in real-time and persist as physical objects on the island platform.
* **Spectacles-Optimized:** 7 dynamic themes color-compensated for the transparent AR display (black = invisible).
* **Height Milestones:** Reaching specific levels (10, 20, 35, 50, 75 blocks) triggers reactive ambient objects.

**The Tech**

* **Stack:** Lens Studio 5.15.1, SnapCloud, TypeScript, and SIK (Spectacles Interaction Kit).
* **Persistence:** Leaderboard system that reconstructs 3D mini-towers from user's top runs.

This project is fully open source. For the multiplayer networking and lobby system, we used our own **Spectacles Lobby Toolkit**.
