Unlike most AYS engines, every engine in the Hydro AYS Engine was coded entirely from scratch* (pun not intended). *This only applies to Hydro AYS Engine versions greater than or equal to 1.3.0. All versions before 1.3.0 are based on the original AYS engine by @SquigglyTuff. Any similarity to code from Hydro Engine predating version 1.3.0 or the original AYS engine is purely coincidental. [1. Notes] - Since there are effects in the song that would have made charting it "almost impossible", I had to make a version that didn't have the low-pass filter at the beginning and the distortion effect in the middle. [2. Changelog] - Idle animations finally work as intended during the intro countdown. - The "hold note fade effect" is back, after the last update removed it. - Updates have been made to various engines.
