About This Game

MUGI, originally released in May 2026 as an MSX2-exclusive cartridge, is now on Steam!

Meet MUGI, born in a weapons factory.

An experimental “ego” was installed… and he realized:

“I don’t want to stay in a place like this!”

Avoid the pesky robots!

Set the batteries into the battery boxes!

Escape to the next room through the opened door!

Can you solve the mystery every 5 stages!?

Action & Puzzle!
