despite the fact that the boss chest arcade game... things look like you can influence them, i don't think that you can? i think they're just based on randomness and your luck stat. for instance, i always was getting 1 item across my normal save file, and never received anything different even after over 40 or 50 of them
in comparison, the 100% save file here, which features luck upgrades, actually gave me 3 items fairly consistently
related to this: i believe that the bombs with "success" and "failure" might also be RNG? i've tried many different strategy, clicked many different places, tried not clicking, tried clicking as soon as possible, and i can't seem to influence it at all. this leads into an issue: the fact that different defeat CGs can only be seen by having the girls interact with these bombs, and have them fail so their clothing gets ripped
so to get new defeat CGs, you need the RNG of the bomb showing up, and the RNG of failing it--and if you want to get the third defeat scenes for Minami (which by the way doesn't seem to work in the barracks? like if you click it nothing happens) and Yuria, you need to get all of this to line up twice in one run
this game has some fun stuff here and there, and i generally like the art (which apparently some or maybe all of it is ai generated yayyyyyyy KILL ME), but this system is legitimately the fucking worst. what kind of fucking hentai game goes "Yeah you need to go through like 9 RNG checks to get all of the scenes!!!!!"
not to mention the fact that the game literally goes "oh yeah hey the final boss is in the next room!!!! you open the door!!!!! COME BACK IN APRIL", while also already planning on having DLC and rubbing it in our face
normally i just pirate games because i don't have the money to spend on h-games like these (or really games in general lmao, lower class moment), but this is a game i think i'm going to pirate specifically because, while it has some solid scenes, i don't think it deserves my money for how aggravating it is
