    Phosfi Demo Update - 2/9/24

    Another update for the Phosfi Demo is live! Following more feedback from players over the last week, this update aims to address several common issues encountered with the demo. Patch Notes Feature Updates Increased jump speed, gravity and "snap" of movement. Also increased base move speed to retain original jump distance and height. Increased inertia of basic movement. As part of an ongoing effort to get movement to feel as good as possible, this update aims to address a common feeling of slowness and floaty-ness. These changes are intended to make the character feel more alive, grounded and responsive Changed how relic equipping is displayed and interacted with. Several players were confused by the relic UI (which needs help). This change should make it more obvious what is equipped and how to equip and unequip relics Increased dash speed while shortening dash duration. This should make the dash feel quicker while retaining the same distance Made boosting off Urchins and jumping off of the Lash ability more consistent Changed default control scheme. Many players had issues with the default control scheme. While the controls are customizable, this change aims to reduce initial frustration. If you already played the demo but would like to switch to the new default layout, you can use the "reset to default" feature in the controls settings. Animation improvements Bug Fixes Fixed an issue with controller deadzones being too large, making movement feel less responsive Fixed an issue with y-axis input on some controllers Fixed an issue where navigating the map could feel erratic Fixed an issue causing players to respawn further away than intended in some areas Fixed an issue allowing players to boost much higher than intended off Urchins and with the Lash
