Leap for Love Game Jam Version Bug Solutions

Solutions:

Title/start screen - simply correct the typo from 'Leap on Love' to 'Leap for Love'.
Water shader - use GLES3 as renderer? Still uncertain with this one as other shaders work just fine in GLES2 on web export.
Buttons - move the buttons on an Autoload class.
Level 2 - by moving the buttons on Autoload class, the rest of the game would be able to access them directly.
Timer - add a condition that whenever the Timer node is ready, wait for any user input before running it.
