This look like bugs or oversights (i didn't find them in the changelog):
When you skip through conversations with either spamming click or the skip button (i think it also happens when "auto" is on), you automatically select succeed on any "checks" (skill, items, etc) that give you the option to pass or fail.
Maybe it's just a design choice, but i usually load back and want to see what happens if you fail the check, and spamming click or the skip button make me go past it. This is not gamebreaking, this is not succeeding when i shouldnt, it just automatically decides and i think it shouldn't happen.
There should be a work around for the player or a limit to the way some enemies grapple you. I haven't progressed that much through the game so i don't know if this is unique to the slime but she is unbeatable in a grapple battle. I have STR 6, END 9 and she outscores me by like 10-15 or more in grapple moves.
I'm all for getting beat in this game, and i find it fitting that a slime is imposible to grapple with, but if she is low on health she won't let you move even if you spam struggle or submit while she uses rest or hold (i literally spam for like a 100 rounds to see if it was an RNG thing). It's weird because she does proggress the grapple at first, but at some point spams rest and hold, forcing a restart no matter what you do.
I think after some turns stucked in the same "grapple phase" maybe make the enemy more pushy, maybe you get a 3rd option to lay both on the ground (so you dont get punished by being winning the fight). Maybe this is unique to the slime because of her overpowering strength and making her "AI" ignore injury in her behaviour through a perk, hability, or something would solve it; whatever the case, don't just end the grapple, at worst give the option to the player to break even if it get's too long.
This is not a bug, but i think the "gallery" (Pervert) would be better if it let you use the arrow keys to move through it. The arrow keys let you move through pages but not in them. If you could put the focus on the inside menus that would make it so the scenes can also be "moved through" and that would be really cool since the are already in order (sort of).
Maybe make the arrows work in the page and if you move out of the page to the right you move to the next one. If you select a character or a scene, make the arrows change focus and move through the scenese.
(When i say "page" i mean the list of characters you encounter, they are sorted in menus that look like pages for how you can "turn" them)
I have no idea how the menus are done, and for some of this things to change maybe you would have to change them or something making them too much work. Outside of the grapple stuff, this aren't problems, just quality of life changes.
