Hi folks, We have recently published a native Linux build of DemonCrawl through the Steam Beta program! You can play DemonCrawl on Linux right now by supporting us on Patreon. We hope to get it ready for worldwide release within the next several weeks. :-)
A couple important notes about DemonCrawl on Linux: 1. We have heard that DemonCrawl has always worked pretty well in Wine/Proton, but certain network features like the leaderboards crash the client, and there are significant slowdowns when hovering some items. We are happy to confirm that these issues are NOT present in the native Linux build. 2. Officially, we only support the latest stable build of Ubuntu. Unofficially, however, you might be able to get this thing running in other distros with a little elbow grease. Please reach out to us if you need any help doing so. Thank you for reading!

• 600+ unique items to discover and collect: whenever you find something new, we'll record it in your Codex for future reference.
  
• 5 Quests & multiple difficulties for a long-lasting challenge.
  
• 50+ exciting stages to explore: think you've seen everything? Then it's time to dive into the Endless Multiverse, where stages are blended together and randomized for virtually unlimited possibilities.
  
• 70+ stage mods to keep things unexpected: from "Abstract Burning Forest" to "Double Dry Ocean" and everything in between - DemonCrawl stage mods can have a dramatic effect on how you approach the game board!

• Open-ended player progression, the roguelite way: find Tokens while playing and spend them on Talents that complement your playstyle. DemonCrawl lets you create multiple profiles in case you'd like to experiment with different builds!
  
• Gamemodes galore: in addition to standard Quests, we've got Endless Multiverse, a daily Hero Trial, an extra-tough 3-stage mode called Beyond, a simple Tutorial, and yes, even a Classic mode for the purists.
  
• 22 unlockable Masteries: enhance your runs with passive effects and charged abilities! Are you more of a KNIGHT or a SURVIVOR? A perilous HUNTER or a penny-pinching BANKER? A glorious FIREFLY or a special SNOWFLAKE?

• Customize your profile with cosmetics: build up your collection of Avatars and Inventories, then get wild with super-rare Paint drops... assuming you're lucky enough to find one!
  
• Online leaderboards for DemonCrawl savants: there's a leaderboard for every quest in Hard mode and above - including the daily Hero Trial. All scores are cross-platform, which means you get to flex on mobile players. (Sorry mobile players)
  
• There's a crafting system too: solve blueprints, then craft your favorite items at will. Available in Hard Mode.
  
• Over 100 achievements and yes they are tough.
