Osteya - abandoned and forgotten city under ground. With main character - Seed you should collect 4 gold keys and find exit.
On your way will be traps, unfriendly enemies and a lot of secrets.
At each level you should collect few keys to open door.
Osteya will be available at Windows, Mac, Linux, Android, iOS.
What are these menus and level selects? In the version on itch.io (Which I paid $5.41 CAD for) there is none of that. Just a level screen with 24 buttons.
Very nice pixel graphic
