Zenless Zone Zero 'copied my puzzle game,' indie dev says, posts a pretty convincing video to prove it

You probably haven't heard of the indie puzzle game Ouros before now, but you may have seen it and possibly even played it in an altogether different game. That's because, according to Ouros developer Michael Kamm, MiHoYo "copied" the game and put it into Zenless Zone Zero, a claim he backed up with some solid video evidence.

The puzzle was added to Zenless Zone Zero in 2025, according to Kamm, but he's bringing the matter to light now because of recent comments accusing him of copying Zenless. Which, he says, is understandable: "Because MiHoYo is an established billion-dollar company, and Ouros isn't well known, I can see why people would assume that I copied them," Hamm says in the video. "But still, it's frustrating to have your work cloned and then credited to somebody else."

Last year, miHoYo copied my puzzle game Ouros in Zenless Zone Zero. Because they are a recognized, billion-dollar studio and my game isn't well known, some people are now assuming that their version is the original, and mine is the clone. I hope this video clears that up.
