Manifesto
Catch every fleeting idea — see it through to a finished game.
No. 01Humans decide. AI accelerates.
Design, concept, art and systems — every decision that shapes a game stays with the founders. AI tools sit beside us as productivity multipliers, helping us build fun games faster and better.
No. 02Ship in small batches.
Parenting alongside building means daily-sized parcels of work. Automated tests verify regressions on every commit, so small confident changes compound into large systems.
No. 03Start small. Go long.
We keep fixed costs near zero and put resources only where they directly affect the work. Start small, ship Steam first, then expand to mobile and console — one core build, recouped over many years.
'Dong-dong' is the moment an idea drifts up in your head — light, bobbing, waiting to be caught.— Studio Statement · 2024

Fantasy Survival Exploration RPG + Turn-Based Card Battler
The night the seal broke, a black fog swallowed the capital. You escaped with the princess, and now you raise a first barrier at an old fortress on the city's edge, turning a bare shelter into a village one hard day at a time. Bring the stricken regions back one by one, push toward the heart of the royal domain, and find a way to end the catastrophe without sacrificing her.
