it used to be 3000~ points to buy at 150~ end game, now it's 24000, for 1 prestige point per game this is needlessly grindy. You're practically forced into multi-classing and most of the time you never get the good drop to fit your multiclass, at least it made sense in single classing, but now you can't really do that anymore can you? Lest you want to grind for hours just for 1 level
I use 150 as an example because in the previous build you'd easily get in 150 for stage 40-50.
I think the stats should return to linear growth and do the new thing you did where buying any one thing adds +1 to every others, that way the cost of entry for multiclassing is slightly higher and not base and the cost of single classing is untouched.
When you have too much EXP Scaling, whenever you gain a(so many) levels (every single kills) it generates a massive lag spike (and Memory Leakage). My browser was taking 12GB of ram just from this game alone.
one of the major causes of lag I can see in this game is the auto-save at each level up feature, when you're done with the king's games and are playing your own game, you get multiple level ups at once. which in turn initiates multiple auto-saves which causes lags.
I think you should switch the "left/right arms on the Dummy", to fit with the Gladiator's left and right arms. Right now they're inverted, or we have to think that we're facing them backward, which is a bit awkward.
