Thank you for your interest in SWORD FLINGER!
We have tested the currently available demo on a Steam Deck device.
At this time, we have confirmed that:
The game launches on Steam Deck
Controller input is supported
Gameplay and stage progression are fully playable
Valve has not yet completed an official Steam Deck compatibility review, so the store page currently displays "Unknown" compatibility status. However, our development team has confirmed that the demo can be played on Steam Deck.
If you own a Steam Deck, we encourage you to give the demo a try!
We are also collecting feedback and impressions from players. Your comments will help us improve the game.
