Update ver1.9 — Jump To Space Steam update #921410

-Some sounds have been lowered. - Adjusted objects that are easily caught by charge jumps. - Changed judgment of some objects. - Rolling cooldown is now 30 seconds (Rolling is prone to bugs, so we intentionally hide how to operate it). - Fixed a problem where the height is moved to the initial position when save & load is performed. If you are at a negative height coordinate when saving and loading, you will be moved to the initial position. Fixed a problem where some subtitles are displayed even if they are disabled in the settings. Fixed a problem where subtitles are displayed multiple times, so the subtitle status is saved and displayed only once. Added one background music track. We are currently struggling with the issue of Steam Achievements not being unlocked.
