SayGames Announces First Vietnam Partnership with Doors Studio to Launch “BagMaster Isekai”

This partnership marks SayGames’ first collaboration with a Vietnam-based studio, expanding the company’s global partner ecosystem into one of the fastest-growing game development regions.

BagMaster Isekai is built around backpack and merge mechanics — a rapidly evolving genre that opens up strong opportunities for scalable IAP-driven monetization. 

Founded in 2024 by Binh Diep, Doors Studio brings a global perspective shaped by over a decade of experience in the games industry. Binh established the studio with a clear vision: to build high-quality hybrid and midcore games with strong craftsmanship and global appeal.

“Doors Studio is a team with a strong creative vision and the ability to execute at a high level,” said Anton Volnykh, Chief Publishing Officer at SayGames. “We were impressed by the quality of BagMaster Isekai from the early stages — both in terms of core gameplay and product potential. This partnership is also an important step for us as we expand into new regions and continue building long-term relationships with ambitious studios worldwide.”

Binh Diep commented: “Entering the global market sometimes feels like sailing into uncharted waters. In that sense, SayGames has been like an experienced navigator guiding us through the journey — like a lighthouse in the storm. We’re very impressed with the range of experts supporting the project, as well as the tools and infrastructure they provide to help us test and improve the game. At SayGames we found professionalism, honesty, and transparency. And we share a similar vision for the future of the game. That alignment is exactly what we look for in a long-term partner.”

The studio has plans to expand its team. Binh Diep notes: “We do hope BagMaster Isekai can one day reach the level of some of the successful titles published by SayGames, such as My Perfect Hotel, Black Deck, and Chainsaw Juice King. And we hope to attract talented and passionate people from Vietnam to join us and build great games together.”

BagMaster Isekai is now available globally on iOS and Android.
