Uoozu is one of those weird little Game Boy games that never left Japan—which is a shame, because it’s oddly charming. You play as this tiny fish trying to survive in a pond, dodging bigger fish and eating whatever you can. The controls are simple, but the challenge ramps up fast when predators start swarming.

At first, it feels almost too easy, just nibbling on plankton. Then suddenly, a pike shows up and you’re scrambling. The pixel art has that classic Game Boy vibe, all murky greens and blacks, which actually works for the underwater setting. If you’re into obscure retro stuff, this one’s a neat little time-waster.
