You wake up in a strange place, You can see a house on a hill. And some floating train tracks. There’s also a giant little area with Stages, and microphone stands, There seems to be different areas. Like a snowy biome. A beach. A cave. And a giant plains area with a strange biome behind it. There’s also a forest and a massive cave area. Seemingly blocked by a stone door. This place is pretty strange Though the question is.

What do you do first?
