  1.2.1 Small patch

  + Gradient Wells now show correct efficiency (0 — 200%) + Punctures now teleport you to your Void Admiration Chancel, rather than the world’s center. You can reposition your Chancel anywhere in the upper world and begin exploring from that location.

  1.2.0 Dark update

  The core change in this update is a rework of the endgame. Gradient wells used to act like a holy grail — once unlocked, they made the game much more linear. That’s no longer the case. Unlocking their full potential now requires exploration. The resources they extract are now based on a completely new resource distribution map. In general, the farther you move from the origin, the richer the sources you’ll find. This new map only applies to gradient wells; regular channels are unaffected. New Entities: Supercritical Kernel – Placed on the dark side. Reveals the resource composition used by gradient wells and collects symbols. Teleports you back to the origin when fed with Reality. Puncture – Marks a cell with a strong resource composition on the dark side. Acts as a foundation for a gradient well on the bright side, doubling its output.. Direct Chasm – An upgraded waypoint. Connects isolated networks to the Inverse Chasm.Other Changes: Stabilizers now display the current surge effect.Fill Director now points to destabilized surges, empty stabilizers, disconnected gradient wells, and punctures. Adjusted the price of the last building to fit the new gradient well mechanics. Slightly reduced prices for gradient wells and the celestial reactors. Reworked resource animation for conductors. Fixed line width issues in some animations. Improved visual hints for building and relocating. Volume slider is now exponential. Slightly boosted Elmerine and Beta-Pylene surges. Fixed a bug where hollow fruits stopped growing when the max number of hollow stones was reached.Quadrillions instead of "a lot".Fixed incorrect stats for "Need a break" achievement

  1.1.3 Offline progress

  It's been a while! I'm working on the mobile version of the game and have added an essential mobile feature that I also want to bring to the desktop version: background progress. Now, when you open the game, everything that happened while you were offline (up to 8 hours) will be simulated until a complete stop or a major event. Offline time also counts toward the "Need a break?" achievement! Additionally, I've updated the game shell version to try and fix a rare bug that caused crashes at certain points in progression on some computers. I also updated the Czech translation, thanks to Kryštof Kubík.

  1.1.2 Instant upgrades and OST

  This update has one major QoL thing: you can now build upgrades without having to construct previous machines first. I hesitated a lot about this change but ultimately didn’t find any strong arguments against it. So if it is not a unique machine or a hollow flower/fruit, you can place it anywhere if you have resources. Thanks to Hernán Marandino the game now has an amazing soundtrack. You may hear it in the background at certain moments. I personally love how it merges with the sound of machines, so sometimes you can't even tell if it's music or just the game itself. Charonite and Qanetite surges are significantly buffed. They could be used to even make pumpless setups (if you don't have too many extractors). Red surges are buffed as well. Other than that: + Surges now remember their stabilizers after relaunch + Fixed a bug when Neophobia didn't appear in the achievements list + Added Norwegian language + Stabilizer in hand now prevents accidental surge collection + You can see the refund amount when upgrading something + Upgrading counts as deletion for RBR achievement (just feels right) + Minor bug fixes
