Well that's interesting. The game's a descendant of the older incremental life sims like ReCycler or Progress Knight, etc. - and as such isn't really an Idle game for the purposes of tags. It's an improvement in that it expands with each playthrough, which leads to my main complaint: Ascension comes out of nowhere, with stats that aren't especially indicative of how they contribute to the final score. (There's some minor incongruities, or maybe I haven't played far enough in, where the prestige bonuses don't quite match what's available in Elder and later; and there should really be a default, toggleable auto-pause on each phase.)
Worth playing though! It's been a while since someone made an incre-sim this playable.

(The specific combo is Cutx2 and Vitamin B, followed up with a Red Snule and Creatine. With enough Kettlebells you just keep drawing your stamina boosts from the discard pile. The Back and Chest gains are just from Gain Train.)
(Yes it's with Leg-End. I dare any of you to get it with Purist!)
