Yeah, you know what to do here.
Stage: Ether Mines
Franchise: Xenoblade
Platforms move up and down around a central spire, which can be stood on. Ether crystals sprout from the walls, you can hit them for items. A mine cart track is also present and you can ride the carts or hit them to make them go and run people over. Liquid ether will occasionally rise up and cover the lower platforms, and it will damage you if you touch it.
Xenoblade needs more than one stage and more than one fighter.
