Subliminal: Episode 1 Demo | Patch Notes v1.3.5

💡 Important Notes

  • Hey everyone! It's been awhile since our last update, but as things get closer to the full release of Episode 1, please enjoy these collection of changes, fixes, and *even more secrets* coming from the full episode.

  • Due to the addition of controller support, we've renamed the "Mouse Sensitivity" option to "Look Sensitivity", with the setting also being reset to its default value -- similar to the save system rework from v1.3, this is a one-time breaking change in preparation for the full release.

  • Additionally, there will be a follow-up update later this month, as v1.4, which will be upgrading various technical systems as well as bringing even more improvements from the full episode, so stay tuned for that!

  • Finally, we would greatly appreciate any and all feedback regarding controller support, as while a lot has been done in this area for this update, it is not a perfect result, so any and all notes will help us greatly! Thanks! :D


🛠️ Changes

  • Added numpad support for the "FPS Limit" setting.

  • Improved several visuals and effects in all levels to match up better with their full release versions.

    • Some items have had limited edits, to avoid spoiling their full episode appearances.

  • Improved Camera Shake and Depth of Field effects.

  • Added additional sound effects for various interactions between the player and the environment.

  • Updated the info and visuals for the Dev Note that appears in the title screen on first launch.

  • Added additional elements to the Collectibles Menu -- still obfuscated to avoid spoilers.

    • Note: Some previously collected items have been reset. This is a one-time change to align with the full episode data format.

    • While there are six to seven total collectibles in the full episode, only three can be found in the demo.

    • Those that choose to migrate saves from the Demo to the full episode, will find that collectibles will transfer over.

  • Added some additional collectibles from the full game.

  • Updated FSR and XeSS integrations.

  • Removed film grain from post-processing settings.

  • Improved several pickup object systems, including some surprises for future systems and better modding support.

  • Improved controller support:

    • Initial support for full UI navigation.

    • Initial support for controller glyph and hint integration.

    • Initial rebinding support, with some key limitations.

  • Added partial Traditional Chinese localization.

  • Enabled Lumen Reflections Async Compute for supported non-AMD cards.

    • Supported AMD cards will have this enabled in an upcoming patch.

  • Minor packaging and performance improvements.


🔧 Fixes

  • Fixed an issue preventing using the keyboard to trigger the back button in some title screen UIs.

  • Fixed some objects clipping in Childhood Memories and The WaterWorks.

  • Fixed two softlocks with the mini fridge in The Basement.

  • Fixed softlocks related to crouch behavior while it is set to HOLD.

  • Fixed a softlock related to one of the doors in The Basement.

  • Fixed several light duplication issues, allowing players to have more light then they should at a given time.

  • Fixed a discrepancy in post-processing settings between the demo and the full episode.

  • Fixed Russian UI text support being missing, when the option was selected.

  • Fixed the back button still being interactable while clicking the "BEGIN" button in the title screen.

  • Fixed several audio, visual, and logic issues caused by unsupported or edge-case player interactions.

  • Fixed certain objects showing the HUD crosshair as interactable when they were not.

    • As an example, the button walls in Childhood Memories now only highlight the crosshair when hovering over the buttons, not the whole wall as it did before.

  • Fixed the title screen still being loaded even when fully loaded into the game.

  • Fixed some objects being incorrectly removed in The Waterworks, when using the ERASE switch.

  • Fixed some light-related visual effects appearing incorrectly in low FPS environments.

  • Fixed the circle cutouts still being usable if not in-range or if not facing them.

  • Fixed not being able to jump on vertically-facing circle cutouts.

  • Fixed focus on certain UIs being lost when clicking on empty space within them.

  • Fixed the back button on certain Title Screen UIs not appearing as the correct color, if exited via keyboard key instead of pressing the button.

  • Fixed remaining cases of non-UI sounds not getting paused properly while the game was paused.


⚠️ Known Issues

  • Crashing on launch or during gameplay for some players.

    • If you encounter this, please send in a crash report to our team.

    • Please also be sure to be as descriptive as possible in your report (When exactly the issue happened, specs, ways we can reach out to you, etc.).

  • Controller Support

    • Full controller support will be released with the full version of Episode 1.

    • The demo contains partial support, and we are aware of various issues with it that will be fixed when Episode 1 releases.

    • You may see improvements to this system in the meantime prior to the full version release.

  • Certain Subtitles do not match the accompanying voice line

    • This is due to some FMOD issues that occurred during packaging. This will be resolved in a hotfix update planned for later this week.
