Welcome to the 9 Day Metroidvania

Metroidvanias are some of my favorite games, and by the success of games like Hollow Knight, Ori and the Blind Forest, Axiom Verge, Dead Cells, and Sundered I would guess that others would also agree! That makes it a prime choice of theme for a GAME JAM!!!

What is a Metroidvania?

Metroidvanias can be complicated, they have lots of factors, and of all the genre's I can think of, Metroidvanias are the hardest to pin down.

That being said looking at existing Metroidvanias, there are a few features most games considered Metroidvanias have:

  • Large interconnected maps that encourage exploration.
  • Progression via Items or Unlocking abilities.
  • Obstacles that need specific abilities or items to bypass.

About the 9 Day Metroidvania

The goal of the 9DMV is to make a game in the style of a Metroidvania, and to use all your game development skills to produce a game in 9 days! 

The Rules

  • Follow the jam concept/theme. The game should be a Metroidvania!
  • Game assets, unless Public Domain(CC0), must be created during the jam.
  • Show common sense and common decency towards others.
  • Have fun!


  • Watch your scope! The game should be a full game, not just a gameplay prototype!
  • Don't stress too much! Remember you have 9 days!
  • Don't overwork yourself!


You can hop over to The Game Jammers Discord! To chat and talk about game development! Use #9DMV on Twitter to share screenshots and updates!


There's also a Crowdforge page! Head over there to find some team members and do the jam as a Group!


  • Can I work with a team?
  • I'm in a team, can my team rate other games as well?
    • Yes. Just make sure they're listed as Contributors on your game.
  • Does my game have to be a platformer?
    • No, although MANY Metroidvanias are platformers, and there is some debate around it, for this jam we consider anything that fits the description given in the 'What is a Metroidvania' section as a Metroidvania
    • By This description we consider the following as Metroidvanias due to their open worlds, progression via unlocks, upgrades, and items, and the need for those to bypass obstacles:
      • Metroid Prime
      • Batman: Arkham Asylum
      • Dark Souls
      • Okami
      • Darksiders
      • Most Legend of Zelda games
