This game runs pretty well on my A06. It’s meant to be a relaxing puzzle game where you breed fish. There isn’t an official aarch64 build, but the source was available at GitHub - jobtalle/Koi: Koi Farm, the koi breeding game and I just had to tweak it to build for “arm64” and what it produced works fine.
I’ve uploaded a precompiled version here (in seven parts):
Although I couldn’t get it to display fullscreen without the window title bar, it scales well to the 1280x480 display. Probably easier to play with a mouse, but it’s playable with the trackball.
