Face the object to interact

You have to face an object and be right next to it. Kingy tested this at a door without moving: clicking while facing away did nothing, and clicking while facing the door played the knock. A step back from the TV did nothing either, even while facing it.

Demo v0.4 introduced the same rule, and the full game keeps it. Many decorations don't respond at all, so a silent click doesn't always mean you're standing wrong.

The protagonist stands at the end of a corridor facing the door at the far right. Dialogue reads: Iván? Are you there? ... I knock but there's no answer.
Same spot, facing the door: the knock plays. Facing away, the click did nothing.Kingy capture · Tenebris Somnia 1.0.1 on Windows, October 19, 2026. Game © Andrés Borghi / Saibot Studios / New Blood Interactive. · Open full-size diagram ↗

Save at the emerald fire bowls

Interact with an emerald fire bowl to save. The first one is in Iván's study, which you open during the opening walkthrough. The save screen has three files and labels each one with the room name and a date.

Save Game screen with File 1 labelled Study, 10/19/26 00:25, empty Files 2 and 3, and a green bowl holding an orange flame.

If you die

Dying shows the title SOMNIUM AETERNUM, then a menu with Retry, Load game and Return to title.

Retry reloads your latest save, manual or autosave. Anything you used after that save, such as a Lavendoleum, comes back, and any fight after it has to be won again.

Menu titled Pause with three options: Retry, Load game and Return to title.

Change language

Pick English, Español, Português or 日本語 on the first boot screen, or change it later under Options › Language. Japanese adds the subtitle 暗闇の夢 to the title logo. The menu only says Português; the Steam store lists the language as Brazilian Portuguese.

Demo v0.4 removed the language option from the in-game menu. In the full game it is back, as the first row of Options.

Options menu: Language English, Controller, Keyboard, Volume 100, Run toggle Off, Vibration On, Back, with v1.0.1 in the corner.
