The Onboarding Update - v.1.1.0
The Onboarding Update - v1.1.0Changes:Tutorial System Implemented. Hopefully this helps better act as a guide for new and returning players. If you are running a fresh save, you will automatically be walked through the tutorial. If you are returning, there is a menu option that will allow you to go through it. Codex window added. Adds more information about unlocked nodes, mechanics, achievements, and more. Mostly just a helpful resource if you want to know more about how things work.Daily challenges added. They are a growing set of small daily tasks you can do in order to earn a new meta currency, which leads us to:Personalization Menu. A new menu that allows you to spend the currency gained from the daily tasks in order to get new color schemes for your system. It's small for now, but its a new way to personalize your system a bit. Over time, I will be adding more themes here, and eventually I would like to expand it to allow for more robust customization options. I hope you all like this small customization feature. Two New Achievements!Fixes:Boot Loop Toggle now properly appears once purchased in Firmware menu.Gain Rate is now displaying properly.Future Plans:As it stands, I will be using the "v.1.1.X" series of updates for expanding, reworking, or adding QOL features for existing content. My goal is to take the existing game to the next level, before moving on to adding some post-game content. I have ideas for how to expand the game past the Singularity stage, but I feel like for the time being refining the existing sytems would lead to a better experience overall. For example: this patch, v1.1.0 has a heavy focus on the onboarding process, and giving players more to strive for in the early game. Next, v1.1.5 will focus heavily on a rework of the firmware tree as it exists. Your skills should stay intact, but the plan is to update the visuals to a more refined and thematically appropriate state, as well as adding various QOL features to make using the firmware ...Read full article on Community Announcements (kealsoft.games)Patch NotesOfficial
Hotfix 4 - v.1.0.6.1
Hotfix 4 - v1.0.6.1Changes:After research and much consideration, I found a solution that is much safer memory wise, has higher upper limits (far above a Googol). Your numbers technically will not change, a conversion will take place upon loading the game if save contains old values, however the counting system will be different. This change should address effectively every number I can imagine anyone would hit in this game. If you run into any issues, please let me know so I can address. But, with my testing so far I have found no negatives effects of this change.Here is the new counting system in its entirety (no suffix) = 1K = 1 Thousand (10³)M = 1 Million (10⁶)B = 1 Billion (10⁹)T = 1 Trillion (10¹²)Qa = 1 Quadrillion (10¹⁵)Qi = 1 Quintillion (10¹⁸) \Sx = 1 Sextillion (10²¹)Sp = 1 Septillion (10²⁴)Oc = 1 Octillion (10²⁷)No = 1 Nonillion (10³⁰)Dc = 1 Decillion (10³³)UDc = 1 Undecillion (10³⁶)DDc = 1 Duodecillion (10³⁹)TDc = 1 Tredecillion (10⁴²)QaDc = 1 Quattuordecillion (10⁴⁵)QiDc = 1 Quindecillion (10⁴⁸)SxDc = 1 Sexdecillion (10⁵¹)SpDc = 1 Septendecillion (10⁵⁴)OcDc = 1 Octodecillion (10⁵⁷)NoDc = 1 Novemdecillion (10⁶⁰)Vg = 1 Vigintillion (10⁶³)UVg = 1 Unvigintillion (10⁶⁶)DVg = 1 Duovigintillion (10⁶⁹)TVg = 1 Trevigintillion (10⁷²)QaVg = 1 Quattuorvigintillion (10⁷⁵)QiVg = 1 Quinvigintillion (10⁷⁸)SxVg = 1 Sexvigintillion (10⁸¹)SpVg = 1 Septenvigintillion (10⁸⁴)OcVg = 1 Octovigintillion (10⁸⁷)NoVg = 1 Novemvigintillion (10⁹⁰)Tg = 1 Trigintillion (10⁹³)UTg = 1 Untrigintillion (10⁹⁶)DTg = 1 Duotrigintillion (10⁹⁹)\TTg = 1 Tretrigintillion (10¹⁰²)QaTg = 1 Quattuortrigintillion (10¹⁰⁵)QiTg = 1 Quintrigintillion (10¹⁰⁸)SxTg = 1 Sextrigintillion (10¹¹¹)SpTg = 1 Septentrigintillion (10¹¹⁴)OcTg = 1 Octotrigintillion (10¹¹⁷)NoTg = 1 Novemtrigintillion (10¹²⁰)Qag = 1 Quadragintillion (10¹²³)Qig = 1 Unquadragintillion (10¹²⁶)Sxg = 1 Duoquadragintillion (10¹²⁹)Spg = 1 Trequadragintillion (10¹³²)Ocg = 1 Quattuorquadragintillion (10¹³⁵)Nog = 1 Quinquadragintillion (10¹³⁸)C ...Read full article on Community Announcements (kealsoft.games)Patch NotesOfficial
Patch 3 - v.1.0.6
Patch - v1.0.6Changes:Quantum-Era upgrades no longer can be upgraded beyond their limits.Token multiplier in I/O at level 30 should no longer cause tokens to decrement.Things that cost more than 9.22e18 should no longer be free due to integer overflow.I/O upgrade limits have been re-introduced for balancing.New "Salvage Random Node" button has been added to the token shop. You can now sell a random node in exchange for a random stat upgrade. This is so that anyone who is over the limit and either wants to go below it, is having performance issues, or wants to give re-rolling their nodes another shot, has an opportunity to do so.Game should not slow down or crash after minimizing and reopening.Fast Path max has been removed. Now will disable if no paths are available.I hope this was able to address the issues you all have been experiencing. If any other issues exist, or arise as a part of this patch, please let me know so I can get them sorted as soon as possible. Thank you all for the support, and the feedback!Read full article on Community Announcements (kealsoft.games)Patch NotesOfficial
Patch 2 - v.1.0.5
Patch - v1.0.5Changes:Prestige feels less punishing.Chance purchases and leftover currency now survive era converts, so Tokens / Caps / etc. keep dropping after you prestige. First Power upgrades are cheaper so the new era actually speeds you up. Older saves stuck with Chance at 0 get a small rescue on load.Permanent Auto-Loop is now a tier 2 upgrade.One purchase, permanent auto-loop, and it stays through later prestiges.Shift-click buy max now works on every shop tab, not just Performance.Convert confirmation pop-up now lists what will reset and what you keep. (Including if there is a node-wipe).Pacing has been adjusted to be less punishing.Currencies now no longer cap at 1.84e19.Game will now create a backup of your latest save whenever a patch releases. In case there are issues, patches need to be rolled back, or other situations. Just a precaution to ensure no players lose their progress due to a patch. These are also uploaded to Steam Cloud.These backups will be stored in your SavesDir folder, and named saveData_patch_{versionNo}.bak.json.To restore your data, make a duplicate of the relevant patch backup, delete/rename the existing saveData.json file, and then rename your duplicate backup file to "saveData"Balancing is a major concern of mine right now, so any and all feedback relating to the pacing is greatly appreciated.Read full article on Community Announcements (kealsoft.games)Patch NotesOfficial

Hotfix 3 - v1.0.4Changes:Game will now save on quit.Way is prepared for Cloud Saves.

I am actively working to address any and all concerns.Read full article on Community Announcements (kealsoft.games)
