Monster Lab Simulator

Hotfix 0.6.2 is now live with fixes for battles, Fulu stats, personalities, player movement and the Windows intro sequence. Battles: Fulus now keep their own personality when entering battle. Bond Level bonuses and food buffs now also apply correctly in the arena. Florhorn's Thorn Shot no longer fires almost continuously. Its cooldown now decreases much less as its Attack Speed increases. Florhorn's Ivy Trap now only affects Fulus within 5 meters instead of reaching across the entire arena. Fulu Stats: Bonded Fulus no longer gain extra Health after taking damage and being healed. Health and Hunger values also no longer display above their maximum. Personality: Rerolling a Fulu's personality no longer leaves the previous personality's stat bonus active. Player View: Fixed the player's hands stuttering while walking with VSync enabled, including on Steam Deck. Intro: Fixed the opening logo animation showing a black screen on Windows instead of playing correctly. Join us on Discord Found a bug, have feedback, or just want to hang out with the community?

A small hotfix is now live with fixes for Bond behavior, battles, the Cleaning Robot, item outlines and a few UI issues. Habitats & Bond: Fulus resting inside an orb placed in a habitat no longer lose Bond XP for being orbed. Habitats now apply only their own Bond bonus, while orbs left elsewhere still reduce Bond XP as before. Battles: Fixed Fulus remaining permanently stunned after being taunted. This could prevent them from taking damage or receiving healing, leaving the battle unable to finish. Cleaning Robot: Fixed the robot taking newly delivered cargo boxes to the furnace and destroying the items inside. Item Outlines: Essences, eggs, food and other items are now outlined reliably when looked at, regardless of distance. Sold orbs and items removed from machines no longer remain outlined. Main Menu: The Continue button now correctly appears unavailable when no save file exists. Tutorial: Mouse inputs now display proper button icons instead of internal input names such as FPS_Mouse_LeftClick.
