ALRIGHT FELLOW HEROES WITH THIS UPDATE WE SHALL VENTURE OFF TO FIND THE BOSS DISTANCE (most effective distance to find bosses) AND WE SHALL SLAY LIKE NEVER BEFORE
With the current changes it seems short and quick runs net you the most RP for your time, leveling just gets increasingly difficult so dying as fast as you can and rebirth immediately is just the best way to farm RP since time and distance don't seem to affect RP gain too much.
So I have no clue what cluster pickup does since the tool tip isn't being displayed for me. (mousing over it reveals box with level and name but no actual description)
 "Idle RPG"){kind=icon}
 "Button Clicker"){kind=icon}
 "Idle Roller"){kind=icon}
 "Sonny 2"){kind=icon}
I'm so sorry for your inconvinience. I updated ver 0.1b1, and I added BigNumber clean up after substract, and changed mouse event. So I hope it fixed.
