Hmmm...It's kinda balanced around having rerolls, but probably reroll is still not as accessible as it should be
I'm curious what's causing the end end-game lag- if it wasn't there I'd find the endless mode a lot more appealing
Are you playing on browser or standalone? The standalone version should have way better performance than browser. Due to how the game calculate stats, there are just a lot of processing when the numbers get super high.
