The brief

Hex-grid tactics crossed with deckbuilding, sold as a paid title with one expansion. Our first Godot production and the studio proof that premium still works on Play.

What we actually did

  • Designed the run structure around 18-minute sessions so a run survives a commute.

  • Wrote the deterministic combat core as a C++ GDExtension — encounters resolve identically on device and in CI replay tests.

  • Shipped full offline play with cloud-save reconciliation through Play Games Services.

  • Handled the paid-app store listing, pre-registration campaign and a staged 5%-to-100% rollout.
