About Fluffy Planet -1

Fluffy Planet -1 is a Windows sandbox simulation made by Under_Formatman in the Others engine. It follows a male protagonist who wakes with no knowledge of the world or himself and must survive and prosper in a constantly changing setting. The design is a hardcore simulation sandbox, giving players broad freedom to explore, build, and experiment. Its visual style is 2D AI CG with furry themes.

The current build is v0.3.1, released September 14, 2026. Development is ongoing. It is English and uncensored. The latest update adds an egg-based birth type, eggs, a wooden standing torch with lightning mechanics, and three tree texture variations. It also raises native resolution to 1920x1080, lets Gekkonids occasionally lay unfertilized eggs, and changes how fertilized eggs are placed, collected, and converted.

Changelog

v0.3.1 +Added a new underlying birth type, egging. +Added eggs. (You can eat them whether fertilized or not.) +Added Wooden Standing Torch, and underlying Lightning mechanics. +Added 3 new texture variation to trees. +Made the native resolution of the game 1920x1080 instead of a much smaller 1152x651 resolution. +Made Gekkonids lay unfertilized eggs occasionally +Made cumming in Gekkonids check if they have an egg in the oven and if so, you can fertilize the eggs via fucking and then they spawn as a placed object instead of a drop object that you can take with E. You can still take the fertilized eggs to your inventory by breaking them but this removes their fertilized state and turns them into an unfertilized egg. (Framework limitations, will fix this later.) +Fixed a serious bug where upon new game the world would generate 2x over itself. +Changed Gekkonid dialogue per personality to be more Gecko. +Made filling a vial now give a choice whether or not you want to fill the vial marked, or generic. Generic gives you a normal Vial of Milk while Marked makes that milk retain which NPC it came from. +Fixed many bugs related to NPCs. +Fixed NPCs under your tribe breaking your buildings. +Fixed a bug relating to NPCs not showing up after opening up a new game over and over again, resulting in the ingame counter for NPC tracking to be skewed. +Made Leaves change color coreresponding to their biome family. -Removed God v0.2.1 +Added Underground (Single layer for now.) +Added Underground entrance/exit points that look like little caves you can press E on to transfer between layers. +Added Rocks +Added Gekkonids (Lizards ) +Added Stone-Age +Added Aggressive Personality (Thank you @rawrfunkle) +Added World Settings +Added QoL changes like Take All/Transfer All buttons to Chests +Added the ability to assign an NPC to another tribe, you need to be 100+ Relationship with them and need to lead them to the tribe you want them to be in. +Added Masonry Table (Required to make stone tools.) +Did alot of engine and undercode changes. (For example npcs no longer get stuck at the tiniest obstacle and start breaking stuff like crazy.) -Removed God v0.1.0 (No longer a concept demo!) +Added a lot of variation to the world. +Replaced canine npc textures. +Added more +relationship talk, such as Inquire which makes it possible to ask the age and pregnancy of the NPC. +Added limits to sexual stamina and talking, no longer spamming them right after the end of the interraction. +Added a sundial to check time. +Added a chest to store items. +Added the ability to give simple commands to npcs with high relationship such as making them follow you or setting their home to a nearby bed. +Added the ability to interract with tribes and eventually control them. +Tribes now starve, scouting makes them gather food, you can also donate food to them by interracting with their den by pressing "E" in the middle of it. +Added sub-type and core-type to biome generation, now there are multiple Core type "Plains" biomes with mand sub-types. +Added swimming. +Added the ability to gossip in NPCs, they can now gossip about eachother about NPCs they know, and this can lead into societal death for certain npcs. +Added the consequences of killing an npc where their enemies will gain +relationship while their friends will get -relationship. (You can kill the rival tribe of a tribe and instantly make them your friends.) +Made Berry bushes always drop one berry at minimum. +Added a cooldown to save and load so no bugs appear if you were to accidentally double click. +Added Load Game and Main Menu button to the death screen. (No more softlock) +Added Berry image variation, poisonous berries have exclusive images that you can learn over time. (There is a 15% chance the poisonous berry gets a normal berry image.) +Added Tree image variation. +Fixed permanent Stamina loss bug upon saving. +Fixed saves not registering. (They also give clear save errors, if you ever get one of those please send them to me, and if your save is not overriding which shouldn't happen in this version, please check the 11th page of this forum, there is a way to still make your save work!) +Removed God. Concept Demo 4 +Added Milking and Suckling +Added Save/Load System +Added Main Menu +Added Randomized Boob Sizes +Added Randomized World Vegetation and Water Color (Unique to per save!) +Fixed NPC AI +Fixed Sleep Bug +Fixed Intense Hunger Concept Demo 3 N/A Concept Demo 2 +Added randomly generated berries unique to per save, some can be poisonus while others can be the OP god food, take the risk if you want to. +Added indicators to NPCs interracting with eachother, they will be showing particles appropriate to their actions. (If it is red the interraction ended badly and the relationship of those NPCs worsened, and if it is green opposite happened, if it is white it was neither bad or good.) +Added 3 new crafting recipes (Leaf Bed, Wooden Axe, Wooden Handle) +You can now sleep on the Leaf Bed to speed up gameplay by 10x +Items are now material based, so if something is "Wooden" they all share the same attributes with minimal variations to keep it fresh. +Added hunger, every action consumes hunger. (Eat everything.) +Pumped up the graphics, added grass sway, moving sea, and some shader dark magic. +Added sexual stamina, no more having sex until there is nothing to fuck anymore. +Added personalities to the NPCs, albeit a bit hard to see or understand. (it is literally just bunch of values dancing in the eternal sphagetti code. I legit have no idea how it works) +NPCs now DO stop attacking you if you are above 20 relationship with them.

Version 0.1 alpha It's hard to call this a game. Most of the time you wander around and starve to death because no food spawns. You can make a weapon, murder the furries, and eat them (I wish I was…

While the base graphics are underwhelming they are entirely functional, the AI generated pics are sufficient, I'm no fan of AI but they do the work fine enough for someone without artistic skill. The gameplay is interesting and has very…
