Features

Linux compatibility

The Linux installer is intended for Linux Mint (including Cinnamon), Ubuntu
and other compatible 64-bit distributions. It requires x86-64, glibc 2.31+,
X11 or XWayland, and a Vulkan 1.3-capable GPU and driver. No particular desktop
environment is required. Linux and Deck installation checks passed in our
Linux VM; Mint has not yet been tested separately.

Steam Deck

Install in Desktop Mode, then add the installed game to Steam and play in
Gaming Mode. No sudo password or Proton is required. Leave forced Steam
Play compatibility disabled.

Always launch the game through Steam Gaming Mode. Starting it in Desktop
Mode can freeze the Steam Deck. Use Desktop Mode for installation only.

New Deck installations use 1280 × 800, 16:10, fullscreen, Vulkan,
Game timing → Original and VSync → Off. These timing and VSync settings
are recommended for the best current Deck performance.

Known issues

• Steam Deck Desktop Mode: launching the game there can freeze the device.
  Always start the game through Steam Gaming Mode. Install in Desktop Mode.
• Steam Deck performance: demanding stages, bosses and cutscenes can still
  slow down. Further performance improvements are planned. A stable 60 FPS
  across the whole game is not yet established.
• Widescreen cutscenes: some scenes can look glitchy outside the original
  4:3 area. This is confirmed in Tails' first cutscene. Select Original 4:3
  as a workaround.
• Stability: bugs and isolated crashes may still occur. Please report
  reproducible problems so they can be investigated.

Saves and bug reports

Reinstalling preserves existing saves and settings. Close the game before
running setup. Backups and save-profile management are available in
Options → Profiles.

Report the version, platform, character, scene and steps to reproduce. For
performance reports, include in-game SIM FPS, timing mode and VSync setting.
Diagnostic reports are optional. Do not upload original game files or personal saves.
