Engine and platform confirmed: Tuanjie Engine, one project across mobile and mini-games

On 23 May 2025 the project settled its engine and platform stack, selecting the Tuanjie Engine for the client.

The first reason was reach: the Tuanjie Engine supports native HarmonyOS builds as well as export to the domestic mini-game platforms, so a single project covers all four targets — iOS, Android, HarmonyOS and mini-games.

The second was what the engine brings on its own: its AnimGraph animation system removes the need to build an animation layer from scratch, letting the team spend its in-house effort on combat, monster AI and scene-asset production instead.

Project 8 therefore never has to retrofit any of those targets late in development — the kind of port that usually means reworking the render pipeline, asset loading and input systems wholesale.
