v 1.0.0.4 Updates
We're back from Toronto Game Expo with some quick bugfixes level tweaks and quality of life updates, thanks to some great playtest sessions! Here's a rundown of the changes: Quality of Life: - Horizontal and Vertical deadzones can now be adjusted for gamepad joystick movement in the settings menu Level Balance: - Additional gems and obstacles added to co-op level Mineshaft - Minor terrain adjustment for Jungle Hoppin Bugfixes: - Left and right movement will now properly respect deadzones (including new updated settings options) - Fixed a game crashing bug for interacting on the custom levels page when you have no custom levels - Gravity inversion will now be reset upon respawn for solo levels Some small but impactful changes overall. This should alleviate some of the frustration with intentional movement and generally make for a smoother experience overall. Have fun out there :)Read full article on Community Announcements (threesided)
