| v0.3.4b-1 Hotfix * Fixed Sterilization failing to enable | — | |
| v0.3.4b v0.3.4b: * Cell population cap for upkeep raised 4x. A 4mm dish now has a cap of 80 cells before maintenance kicks in (n = dish size * 20) * All new culture options should unlock now upon tutorial completion * Pixelation filter no longer applies to UI. Removed UI pixelation option (leftover meme option) * Fixed acidic pH culture preset option dropping on some screen sizes | — | |
| v0.3.4a-2 Hotfix * Fixed box select movement commands | — | |
| v0.3.4a - Hotfixes v0.3.4a: * Fixed sterilization not blocking bacteria spawning * Rebalanced contamination rates to be less demanding * Fixed bug where abandoning contracts could result in net positive Biomarks * Mutagen now unlocks upon tutorial completion * Fixed bug where specimens wouldnt be added to Cryobank from Biomarket orders * Updated contracts to reflect recent changes | — | |
| v0.3.3: New tutorial! Hey everyone! I have been working on updating the tutorial and reinforcing the game loops, so I hope this update helps to clear up a lot of the confusing aspects of the game. I look forward to hearing everyone's feedback! v0.3.3: * Added guided tutorial (WIP) * Cryobank rework - now limited to 7 unique specimens preserved at a time * QuickStart moved to new lab option * Harvesting cells with G… | — | |
| v0.3.2: Hotfixes + Quickstart v0.3.2: * Added quick start option * Reduced maintenance costs * Implemented suspected fix for cells freezing on culture death, monitoring results * Fixed various broken or outdated contract objectives * Performance improvements * Tutorial tweaks * Fixed crystal heat bug * Visual tweaks | — | |
| v0.3.1c v0.3.1c: * Bug fixes and balance tweaks to improve cell viability | — | |
| v0.3.1b v0.3.1b: * Bug fixes * HUD improvements * Tutorial improvements * Visual tweaks | — | |
| v0.3.1a v0.3.1a: * Tweaked temperature and pH environmental damage to be more punishing out of range * Tutorial sequencing and language improvements * Various UI fixes * Visual tweaks | — | |
| v0.3.0b v0.3.0b: * Tutorial hint text reworked * Balance fixes * HUD improvements * Bug fixes | — | |
| v0.3.0a - Bug fixes and visual tweaks v0.3.0a: * Plasmodia retuned so they don't immediately die anymore * Fixed endosymbiosis bug where bacteria would float outside of their host cell and produce huge streams of particles * Fixed bug causing bacteria to be mono-typed * Fixed bug causing cells from starter strains to show up as unregistered/diverged * Improved selection behavior * Visual improvements for contrast and readability *… | — | |
| v0.3.0 "Pathogenesis" is here, with a new tutorial and UI! (WIP)major Hey everyone! It's been exactly a month since the last update, and there is a lot to share. Most of the feedback has been from playtesters who are confused, so I have been working on a new tutorial to hopefully help out with that! I also have been working on streamlining the UI and improving clarity wherever I can. This is still a work in progress, but it's enough of an improvement over the las… | 23353882 | |
| v0.2.9a * Balance: - Reproduction cost now correctly accounts for organelle biomass - All cells now influence local pH through metabolism (was restricted to pH-adapted cells). Reduced membrane permeability environmental damage multiplier to compensate as plasmodia were disproportionately affected - Nutrient metabolism waste flow: aminos -> acidic, sugars -> basic, lipids -> neutral * Contract objective… | — | |
| v0.2.8-4: Performance and balance hotfixes This is a small hotfix with a few easy wins for performance and balance. v0.2.8-4: * Various performance fixes * Balance: - Cryochondria are more rare - Corpse deposits return more basal substrate - environmental damage particles now escape collectors (increased emission speed) - pH environmental damage significantly increased * Tweaked contract objectives and language, rework still in progress | — | |
| v0.2.8 v0.2.8: * Added crystal system: persistent environmental generators * Balance tweaks: - Reduced organelle maintenance cost - Reduced movement cost by 10x (was previously 5x+ base maintenance cost) - Increased collector attraction speed - Plasmodium branches take damage from enzymes - All cells now have some basal absorption. Higher basal absorption requires increased membrane permeability, resu… | — |
