Yohjo Simulator is, essentially, Goat Simulator with a young anime girl instead of a goat.
You’re given a sandbox to roam around and cause as much destruction in as you like. The appeal here are the unreliable physics that cause strange effects such as hovering tables and character models stuck halfway inside the floor.
The young girl, as with the goat in Goat Simulator, is fond of headbutting. As you’ll see in the trailer above she’s got quite a bit of force on that headbutt too.
Yohjo Simulator is one of the Japanese indie games showcased at Comiket 88.
