　　This game was made for the GMTK jam 2019, with the theme "only one". What I made is a metroidvania where you only have one key for all the locks. You must carry it with you through a maze-like dungeon, and upgrade it along the way to unlock more metaphorical locks.

　　Here is a map in case you get lost:

　　The story:

　　You're in search of the legendary Keymaster who will save the world. But upon arriving in his dungeon, you only find his most prized possession, the master key. It can open any lock and can be upgraded with various musical clefs which you will find along the way. Albeit twice your size, the key can be easily carried because it is made of carbon fiber mythrill, the hardest but also lightest material known to man. However, you must account for its huge size when moving around, turning the dungeon into a puzzle.
