It really isnt, especially when thats not the goal. Ive played roguelikes before and speedrun games like sekiro and elden ring. What really kills this exercise with karryn's is the sense of being railroaded. Unlike the former, you cant circumvent the pitfalls in this game through skill or planning, they are going to happen - eventually. You are just given the illusion of being able to play it differently, which you'll only realize once youve already wasted inordinate amounts of time.
By design, failure is guaranteed - and doing ok is simply kicking the can down the road. So in a sense it feels more akin to the NieR games, where you are required to play the same gamefile ~4 times to get the full ending...and to get it, you have to agree to have all your progress data and save files permanently erased. Actually this woulda been hilariously fitting for this game.
And i can almost stomach it if the whole thing wasnt purposely organized to waste huge chunks of a person's time "just because" - everything is gated behind a timesink and the jobs are the most asinine example of that - a daily drudge of endless click-heavy memory game, with stage hazards, that must be repeated daily to get any sort of palpable bonus from them, and even it doesnt feel even remotely worth it. Yet do them you must, because what else are you going to do with 11-16% fatigue and 70% pleasure.
Whats hilarious is that this mandatory timesink extends even to the H part, because even if people are looking for a quick fap, unless they plan to live in this game, they will still need to spend ~2hours purposefully losing fights over and over and reading how enemies paint the floor, before they get to see something. So, amusingly, its equally frustrating for all groups of interest.
