What It Is

rtsoft.com is the official website of Robinson Technologies Corporation. The team is based in Kyoto, Japan, and is run by Seth and Akiko Robinson. It is a long-running independent game development studio. The site showcases its free games, early BBS games, mobile games, open-source frameworks, experimental hardware/AI projects, and developer blog. Its best-known related works include Dink Smallwood, Dungeon Scroll, Mind Wall, and Growtopia, which was co-developed with Hamumu Software and later acquired by Ubisoft.

Core Features

The site mainly serves as a “project directory” and “developer archive.” Users can browse sections such as Web Arcade, Older Things, and Gamelets to find games and older works. Dink Smallwood HD offers multi-platform versions and is open source. Dungeon Scroll, Mind Wall, and other titles provide free web or downloadable versions. Proton SDK is a cross-platform C++ game framework aimed at developers. The site also includes LORD/BBS FAQs, a video usage policy, the author’s blog, and GitHub links, making it a valuable resource for researchers of retro games.

Pricing

Based on the collected content, most of the games highlighted on the official site are free, with clear statements such as “free with no ads/spyware.” Some projects are open source, with source code available on GitHub. Historical works such as LORD and TEOS have been sold to other companies, so registration codes, licensing, and after-sales support are not handled directly by Robinson Technologies.

Pros and Cons

The strengths are its deep long-term catalog, covering multiple eras and formats including BBS, PC, mobile, web, MMO, VR, and AI tools; a high proportion of free and open-source projects; and the developers’ transparent attitude, with even old projects, unplayable projects, and historical FAQs preserved. The downsides are that the site structure has an early-internet feel, and its navigation and information density may not be friendly to new users. Some older projects have shut down, external links may be dead, or the content may only have commemorative value. It is not a modern distribution platform like Steam or itch.io, and does not offer a unified account system, purchase system, or standardized customer support.

Who It’s For

It is suitable for players who enjoy retro indie games, Dink Smallwood, or the history of Growtopia. It is also useful for game developers studying the long-term output of a small independent team, open-source C++ game frameworks, and the author’s experimental projects. If you are simply looking for popular modern commercial games, this site is not the best first choice.

Access from China

Judging by the nature of the site, rtsoft.com itself is a standard independent game studio website and is expected to be directly accessible. However, external links such as GitHub, Twitter/X, Mastodon, Bluesky, and YouTube may be unstable or require a proxy when accessed from mainland China.
