Twin Realms: Echo Dungeons

Inspiration

We love roguelite dungeon crawlers, but they usually live on a single screen: either mobile or VR. With Twin Realms: Echo Dungeons we asked a simple question: what if one dungeon echoed across two realms – quick snackable runs on your phone, and deep, embodied raids on Meta Quest.

What it does

Twin Realms: Echo Dungeons is a cross-view roguelite set in a world where every run is a new “echo” of the same dungeon.
This submission focuses on the Horizon Worlds mobile experience: short 2–4 minute runs with tap-to-move combat, random upgrades, and a cozy camp where you invest your earned resources into long‑term progression.

How we built it

We started by designing the core game loop and progression system so it works both on mobile and in VR.
On the Horizon Worlds side, we focused on portrait‑friendly layouts, 1‑hand controls, and clear UX for quick sessions. In parallel we drafted the Quest architecture for a hand‑tracked, room‑based dungeon experience and a mixed‑reality “tabletop” camp that lives on your real‑world desk.

Challenges we ran into

Designing controls that feel great on a phone while still mapping cleanly to future hand‑tracked VR interactions was tricky.
We also had to be very intentional about session length, pacing, and visual clarity so the dungeon stays readable on small mobile screens.

Accomplishments that we're proud of

We’re proud of creating a coherent IP – Twin Realms – that is designed from day one to span both Horizon mobile and Quest.
The current prototype nails a clear short‑run loop, a satisfying sense of progression, and a strong visual/story identity that we can carry into future platforms.

What we learned

Designing “mobile‑first” inside Horizon Worlds means obsessing over onboarding, thumb reach, and how fast players get to the fun.
We also learned that thinking in terms of shared systems (loop, progression, worldbuilding) instead of single devices makes it much easier to plan future VR and mixed‑reality extensions.

What's next for Twin Realms: Echo Dungeons

Next, we plan to build the full Quest experience: hand‑tracked bow and spell combat, a mixed‑reality camp diorama using Spatial SDK, and a passthrough “rift” that turns your room into a gateway to the dungeon.
On top of that, we want to deepen co‑op runs, seasonal challenges, and cross‑progression so players can seamlessly move between mobile and VR while staying inside the same Twin Realms universe.
