my calculation is based on Pythagorean with a .1% margin in favor of the player.
The black circle is just an indicator.
Tip: clicking far beyond the max range ,outside the ui circle, will ensure max distance jump.
Tip: try to reach the edge of a lily with a small hop to ensure the best chance of reaching a pad appearing out of range of the UI circle
I'm glad you found the game to be enjoyable and difficult! <3
