About this game
Spore Valley is a bite-sized resource management puzzle in which you grow an alien slime mold over a hex-based grid while carefully managing a turn-based metabolic resource system.
Will you starve and dry out, or will you complete your slime's life cycle, casting off spores into the wind to give rise to the next generation?
Your home planet is an arid, sun-blasted planet baking under a youthful star. But here and there, underground rivers dart to the surface, carving the desert into narrow, habitable valleys.
Your slime germinates in just such a valley, and you must steward it through its lifecycle. It is a complex sci-fi organism inspired by real-life examples of modern and fossil fungi, slime molds, and lichen, and is among the first complex organisms to make a living on this harsh young world.
Spore Valley blends a turn-based town-builder with a resource management puzzle. Your world is a map of hex tiles across which you must grow your alien slime, choosing from a variety of different biological forms to grow, each with their own unique requirements, constraints, and contributions to the puzzle of your survival.
Resource Management Puzzle
There are 5 core metabolites, which are resources critical to your slime's biological functioning. Different forms of your slime produce and consume different metabolites each time you progress to the next turn.
Running out of any of these resources can cause your slime to lose portions of its body or completely starve to death, so it's important to produce enough metabolites. But beware: if you produce too many, metabolites can build up to toxic levels, which can also cause your slime to suffer.
Metabolites depend on interacting with the slime's environment, and not all resources are infinite, so you will need to balance your rates of growth, production, and consumption carefully if you want to grow complex enough to complete your slime's life cycle.
Features
5 metabolites to manage
15 biological forms for your slime to use
Turn-based growth and resource management
Procedurally generated maps

Support for mouse & keyboard, keyboard only, and mouse-only controls
Difficulty & tutorial settings
Developer cats in the credits
Spore Valley is a short game, meant to provide a complete experience of puzzling play in a single extended sitting. Still, random maps can add variety to replays, and you can use difficulty settings to challenge yourself to become a more efficient slime grower, whether for your own satisfaction or in pursuit of achievements.
Spore Valley first germinated as an solo developer entry in the Ludum Dare 54 game jam. It has since been rebuilt from the ground up with new mechanics, a new 2.5D art style, a new UI paradigm, and professional art and music. It was developed primarily using open-source tools, including the Godot game engine, Inkscape, Gimp, and Audacity.
This is Lystrosaurus Studio's first commercial game project. The studio is committed to understanding players' experiences, learning to make better and better games, and delivering quirky games to quirky people. Please to share your issues and your feedback with the developer!

Patch NotesOfficial
Patch 1.3 - Music & Controller Update
Hey folks! We've got a nice, somewhat larger patch for Spore Valley today. First off, we've got some great updated musical tracks courtesy of the excellent Matthew Boerner, aka Freshman Biology! The new tracks will also be available through his own platforms, if you want the tracks for yourself! Beyond that, this update also includes finalized controller support! Several parts of the interface have been updated to either work with or make more sense when using a controller, without impacting the mouse+keyboard experience. The whole game can now be played with a variety of input devices: Controller Only (tested on an XBox controller, but the engine supports all common modern controllers) Keyboard Only (that's right, no need for a mouse!) Mouse Only (this was already possible, and is still supported) Any combination of the above! None of the input devices lock each other out; you should be able to switch seamlessly between any of them. Finally, we've got a few other changes and fixes: When selecting a Bioform that's disconnected with your body, the selection card will look visually different, and the gameplay tooltip will note and explain the disconnection A new hint appears during gameplay the first time the player encounters an Infestation Bug fix: The game camera no longer moves around in the background when navigating a non-gameplay menu Bug fix: Solved an issue where selecting a tile with nothing on it would sometimes show the Toxicity warning in the tooltip Bug fix: Fixed a generally silent error with controller menu navigation that might have been impacting gameplayRead full article on Community Announcements (Lystrosaurus Studio)Patch NotesOfficial
Patch 1.2.5
Content changes: The tutorial now has a longer intro cinematic, with more information about a normal game's win condition If hints are enabled, encountering a Cacomorph will trigger a new hint suggesting how to deal with it The middle mouse button can now be used to drag-pan the camera around rapidly, in addition to other methods Cacomorph description text updated with more explicit instructions Bug fixes: Cacomorphs should no longer spawn on disconnected sections of the body Cacomorphs should now spawn in the correct amount When a Bioform is lost due to Deficiency, any other Bioforms that are now cut off from the body are correctly highlighted Moving the Sporeling around now correctly triggers fission and fusion logic (i.e. whether other Bioforms are connected to your body or not) Visual flashing to indicate Infestation now correctly triggers on bioforms built on already-infested tiles, and on loading a saved game You can no longer select a Bioform to grow while a tutorial panel is upRead full article on Community Announcements (Lystrosaurus Studio)Patch NotesOfficial
Patch 1.2.4 - Fixing Game Breakage
The urgent purpose of this patch is to resolve a serious bug where the game fully breaks if you lose after the Lystrosaurus has despawned (the HUD either darkens or disappears entirely, and the world can't be interacted with), effectively preventing you from restarting a new game unless you restart the entire application. Beyond that: Added an additional arrow in the third phase of the Tutorial to remind players that they need to click Next Turn to get more resources and progress Fixed a collection of issues where in-world GUI pips, desiccation dust, and bioforms animating their own disappearance persisted into new games after restarting (more commonly after losing) Fixed an issue where the game's actual current turn could fall out of sync with the turn counter displayed on screen Fixed an issue where the effects of the Lystrosaurus' "present" aren't reflected in the resource HUD Fixed incorrect text that appears when trying to grow a Bioform in an unsuitable location Fixed some typos in various stringsRead full article on Community Announcements (Lystrosaurus Studio)Patch NotesOfficial
Patch 1.2.3
Further tweaks to the new tutorial experience, with more guidance on some sticking points surrounding Lipode placement requirements, and metabolic stagnation.Read full article on Community Announcements (Lystrosaurus Studio)Patch NotesOfficial
Patch 1.2.2
A tiny urgent patch to fix a problem where the previous patch resets player data in a way that caused the main menu to break.Read full article on Community Announcements (Lystrosaurus Studio)
