Spirefall runs natively on Steam Deck
The Spirefall demo ships a native Linux/SteamOS build — no Proton, no compatibility layer. Steam picks it automatically on Deck and on desktop Linux, and it runs in the Steam Linux Runtime, so there is nothing to configure: install and play.
Here's exactly what that means, and what we tested.
Full controller support
Every screen in the game — menus, the tavern map, deck panels, shops, settings, and matches themselves — navigates on the gamepad with a visible focus ring and a sensible landing focus. No touchscreen, no trackpad-as-mouse, no on-screen keyboard required anywhere in the demo. Pressing 'Y' now triggers tooltips on Deck.
The pad map, everywhere in the game:
- A — confirm / play the focused card
- B — always backs out exactly one layer (close a panel, cancel a prompt — never further than you meant)
- Y — inspect anything on demand: cards, fortresses, abilities
- Select — toggle attack-all during your attack phase
- LB / RB — ride the rails between board zones and menu chapters
- D-pad / left stick — spatial navigation across the board and menus
Built for the Deck's screen
The UI was reworked for 1280×800 handheld play, not just scaled down:
- At handheld heights the fortress crest and commander card pop out of the banner and overhang the battlefield — more presence, no board rows sacrificed.
- Ability gems wear compact two-letter sigils on short screens; the full text is always one Y-press away.
- A UI scale setting in Settings lets you tune the whole interface to taste.
- Panels, sliders, and scrollable lists are all engageable with the pad — including the block-assignment cycle during combat.
How we tested
Deck support wasn't a checkbox pass — the demo went through eight rounds of on-device Steam Deck audits, each one played by hand on Deck hardware, with fixes shipped between rounds: focus-trapped overlays, pad-reachable tooltips, scroll regions, safe defaults on confirmation prompts, and the B-button contract above.
Saves
Steam Cloud backup is enabled for your demo save. Progress carryover between a Deck and a Windows PC is in testing — we'll confirm it in a patch note once we're satisfied it's solid.
Found something off?
If anything reads small, focuses wrong, or fights the pad, we want to know — Deck play is a first-class target for us, not a port. Tell us on our Discord or in the community hub discussions, and include your UI scale setting if it's display-related.
Back to the Tavern — it plays great on a couch.
