An AI-generated version of the work-in-progress indie game Typing Room appeared on Unityroom days after its developer shared early footage. The creator defended the copy as revenge for the original developer's past fangame. Japanese indie developers have expressed concerns over AI content on the platform.
Content creator Kamaboko has been developing Typing Room for about a month and shared its first development video on YouTube on February 26. On March 4, a user named Kamaboko Kōsatsu Kōsatsu uploaded a version titled Typing Room to Unityroom, a platform that hosts games with potential ad revenue support. The upload, as spotted by Automaton, was created using AI prompted by Kamaboko's videos and user manual, taking just two days to produce despite being free-to-play. In a YouTube video responding to plagiarism accusations, Kamaboko Kōsatsu Kōsatsu confirmed using AI for everything and called Kamaboko 'lazy' for taking longer to make games. They justified the copy as revenge, citing Kamaboko's earlier Palworld and Pokémon crossover fangame that used official assets. The incident has sparked backlash among Japanese indie developers on X. Many worry about lax AI content rules on Unityroom, with the rip-off still available. Indie developer Strawberry Sakura wrote, “I’ve come to feel nothing but despair... When you publicize a project at such a rapid stage like I did, or spend too much time on development, it ends up getting stolen like this, huh… I feel anger welling up toward those using generative AI.” Others echoed fears of sharing work-in-progress videos online.
