Hi, this is a simple stage that I made
this is Mt.Sagiri from demon slayer: it is a large mountain in the anime and manga series Demon Slayer. It is located in a largely uninhabited region, and the air is extremely thin near its peak, making respiration difficult. The mountain is used by Sakonji Urokodaki to train aspiring Demon Slayer fighters, where students are tested by chopping down a rock with a katana. Those who succeed in this challenge are sent to the Final Selection, where they are accepted as Demon Slayers. If students fail or die during this selection, their spirits are trapped within the mountain

for Mugen 1.0 ( i didn't test it for the others)
Made for 640x480 Playable in 1280x720, 1920x1080
