| When | Note | Build | Update size |
|---|---|---|---|
| May 14, 2026 | EA1.2.57 New text lines were created for every | symbol fix We had a terrible bug in which all texts were spilling out thanks to a new steamdeck regex we introduced in the large patch to autodetect and change certain texts depending on if the player is using a deck or not-now fixed. Sorry for having to see so many badly formatted texts! You can reset your progress using the X button in the profile section if you feel this bug gave you any trouble.-QI teamP |

| Apr 23, 2026 | EA1.2.55 Game now finally has cats Small fixes and changes to narration, puzzles and story. On the 4th (if things go well!) we go live with a Large patch -> this will make game fully playable offline, accounts can be reset, and entire game will have tailored UI and setup for Steamdecks. We need to plan a server reset soon. Game is now in top notch condition to learn quantum without any background in anything (esp now that it has ca |

| Mar 25, 2026 | EA1.2.51 fixed memory leaks, improved intros this patch should forever address the laptop overheating problem some users were reporting after long play sessions |

| Feb 9, 2026 | EA1.2.49 New letter, improved content, offline work and translations New in .49: -letter from Sage of Reasons -a few changes to puzzles that were too hard too soon -difficulty curve adjustments We are now preparing the offline mode for deployment (maybe another month of work?) and figuring out if the 400p+ written content within QO can actually be translated to languages beyond English. This will be quite a heavy project to undertake and I hope we won't let you dow |

| Jan 5, 2026 | EA1.2.46 many QoL improvs most won't notice Focused on the first 5 modules and a few other small insignificant tweaks. Offline mode soon ready for deployment |

| Jan 2, 2026 | EA.1.2.45 Improved SWAP challenge, wording changes, sage letter impros HNY! SWAP challenge has been remade, you can no longer cheat (everything needs entanglement now) Fixed some issues with the letters and overall wording |

| Dec 30, 2025 | EA1.2.44 Reworked Sage Letters to now express qm foundational ideas Many found the sage letters to be too hermit-y and their language esoteric. This is no longer the case. I think this new rework combines really well with the new quote system the game is using to make for a complete immersion into this playground of quantum logic. Happy New Year everyone! The game is in an amazing state rn. Offline mode, metrics system overhaul and our first esports like competiti |

| Dec 26, 2025 | EA1.2.41 Oracle, Erases the data entries final, offline mode 90% ready! This holiday season I'm enjoying working at this game more than anything for some reason. Hence you'll find in this patch further improvements to the learning curve, and a really verbose way to explain one of the hardest concepts in quantum algorithms development: What REALLY is an ORACLE? Check the Encyclopedia of the game (now sitting well at above 300pages) for the full description and if there |

| Dec 7, 2025 | EA1.2.40 The wordless tutorials now explain game mechanics Realizing from several reviews that players get frustrated if they don't get explanations right from the start, I added deeper, beginner-friendly tutorials around the first node. Mechanics of the Fracture I & II now explain the game mechanics without using any quantum theory. Designing a good learning curve is extremely hard, especially when players come in with wildly different backgrounds. Some |

| Nov 23, 2025 | EA1.2.39 Press R to advance texts, don't click symbols anymore! You no longer need to click buttons to advance texts, simply press the R key! Improved the narrated module, eliminated typos Every time you entered a new module it used to say "Learn to Fly", now the name of the puzzle is displayed instead. In the map the new hold right click to pan option is shown Panning over UI is no longer possible holding right click |
