Jumana Port Devs Recall 3 To 4 Month TGS 2025 Demo Sprint
A small team shipping a demo under a hard convention deadline and then releasing the full 1,600 yen game is the working shape of the indie roguelite market right now, where a short, friendly run is the pitch rather than a hundred-hour commitment.
Reporting from 1 source: Game Spark.
Red Dunes Games and Agate released the 2.5D roguelite action game Jumana Port for PC and PS5 on September 8, priced at 1,600 yen with Japanese language support. Director Shandhi Sayogo told Game Spark the game draws on the Arabian tradition of pearl diving and on Cult of the Lamb, and that the team built a playable Tokyo Game Show 2025 demo in roughly three to four months.
Jumana Port puts players in the role of Mansour, a young man pulled into events beyond his control who sets out to save the world, diving sea areas and fighting what waits on the ocean floor. Cleared missions unlock abilities and equipment, and stronger gear opens harder waters.
Director Shandhi Sayogo frames the design around access: runs (called dives) are short, and the target is newcomers to the roguelite genre without leaving hardcore players bored. The team started work around May 2025, spent the first month on concept, then had to produce a playable Tokyo Game Show 2025 build in the remaining three to four months.
