|---|---|---|---|
| Game update | v0.4.0b v0.4.0b: * pH tolerance and temperature tolerance gene mutations changed from multiplicative to additive to try to improve the bias of cultures towards acidification * Replication cost now scales with population density so overcrowding should be less of an issue * Added the ability to remove crystals. Right-click while holding the crystal tool deletes any crystals near the cursor. NOTE: The den… | 23828947 | |
| Game update | v0.4.0a v0.4.0a: * Improved HUD behavior for different aspect ratios * Cursor tooltip hides on drag (F2 to show/hide) * Added attribute examples to "show me" guides * Blocked killing cells during tutorial to prevent accidentally breaking it * Compacted nucleus inspector display * Fixed plasmodia particle production stopping prematurely * Fixed plasmodia immortality bug * Minor description tweaks * Subs… | 23790143 | |
| Game update | v0.3.5 v0.3.5: * Bacteria rebalanced to reduce the amount of active attention they require. Bacterial blooms are more rare * Reduced maintenance cost burden so labs can comfortably afford significantly higher cell counts * Biomarket, contracts, Cryobank, and glossary panels all merged into one "Manage" screen with tabs * Scaled down culture sizes significantly for improved population dynamics * Improv… | 23722705 | |
| Game update | 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 | 23645623 | |
| Game update | 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… | — | |
| Game update | v0.3.1c v0.3.1c: * Bug fixes and balance tweaks to improve cell viability | — | |
| Game update | v0.3.1b v0.3.1b: * Bug fixes * HUD improvements * Tutorial improvements * Visual tweaks | — | |
| Major update | v0.3.0 "Pathogenesis" is here, with a new tutorial and UI! (WIP) 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… | 23353878 | |
| Game update | v0.2.7a I've continued working on getting the simulation stable in the long term. Performance still drops but I'm pretty sure that it's from slime mold's being unbalanced now, so I'll be working on that next. I ran the simulation over night last night and found some more GC leaks, and fixed most of it today. I haven't had a chance to run it for very long, but so far memory use is noticeably lower and d… | 22703245 | |
| Game update | v0.2.6b v0.2.6b: * Stability improvements: - Fixed memory leaks causing gradual degradation over long sessions - Fixed various death/spawn lifecycle edge cases that could cause errors * Performance improvements: - Significantly reduced CPU cost of slime mold networks at scale - Fixed GPU upload path running at full cost every frame - Particle system now scales to actual cell count instead of fixed max… | — | |
| Game update | v0.2.5 v0.2.5: * Reworked contract system to offer more depth and variety (Still very WIP, needs feedback and testing) * Adjusted weighting and masking for automatic strain grouping * Increased digestive enzyme damage * Fixed contract timer bug where time-based objectives would be impossible due to their timer being too short * Fixed major performance bug where hidden panels were being redrawn every f… | — | |
| Game update | v0.2.4 v0.2.4: * Expanded tutorial and adjusted explanations for clarity (need feedback) * Added pop-ups to major panels on first open with WIP drafts of explanation blurbs * Continued work on contracts. Fixed some contracts being impossible due to the culture lacking prerequisite cells, tweaked progression and available objectives. Contracts now automatically detect if an objective is completed on ac… | — | |
| Game update | v0.2.3a v0.2.3a: * Lab Mode fixes: - Removed spacebar spawner from lab mode - Added main menu button to resume last active lab - Made button to open saved labs more obvious, now says "LOGIN" - Improved lab save structure, fixes culture bleed between labs * Strain tracking fixes (formerly species tracking): - Strain Registry now correctly saves marked strains across *all* labs (excluding creative lab, t… | — | |
| Game update | v0.1.6 v0.1.6: * Major performance improvements * Enzyme combat improvements * Energy particles visual adjustments * Slime mold fixes * Experimental new game settings (Placeholder UI) * pH and temp deposits updated * Memory usage improvements * Various bug fixes Known issues: * Mitosis jitter during fission * Enzyme particles buggy * Population balance off (boom/bust cycles) * Performance degrades at… | 22036305 |
