Play Jikuu Senki Mu (Japan) Online
You lead a mismatched crew of warriors through time, turning enemies into allies mid-battle—each fight’s a fresh puzzle with samurai clashing against robots. The pixel clashes and chiptune tracks make it feel bigger than a Game Boy cart.

Jikuu Senki Mu is one of those Game Boy games that makes you wonder how they fit so much into such a tiny cartridge. You start off leading a ragtag group of warriors—samurai, knights, even futuristic soldiers—through time, jumping between eras like some kind of tactical history teacher. The first battle feels familiar if you've played Fire Emblem, but then you realize you can recruit enemy units mid-fight, and suddenly every skirmish becomes this puzzle of who to convert to your side.
The pixel art holds up surprisingly well, especially the little animations when units clash. And the music? That classic Game Boy chiptune sound, but with these weirdly catchy battle themes. It’s all in Japanese, sure, but the menus are simple enough to fumble through, and there are fan translations floating around if you really want the story (which is bonkers in the best way).
Honestly, it’s a shame this never left Japan—it’s got more personality than half the strategy RPGs that made it overseas. If you’ve got a soft spot for obscure retro gems, this one’s a blast to dig into.
