Art is top notch.
Would like some more visible stats and numbers. Like, what exactly does increasing the chance to find shiny cosplayers do? 3500 cash and 5 stickers is quite a big investment and from what I can tell there isn't like a max amount of times you can buy the books so.. what exactly does that do? Same thing with the combat HUD where it's kinda unclear what buffs/debuffs you have, what's on them etc.
Also some more mention of the shiny/rare cosplayers would be nice. I played all three previous versions of the game and I had no clue there were cosplayers/enemies beyond the 4 main ones.
Also, I beat shiny Jesse and it didn't really seem to do anything? She didn't appear in the shop in th R-room, and I don't think anything there can be clicked?! Unlike others, there didn't start appearing an echo version of her when I defeated her? I defeated shiny Joy, which made the cross in the room in the shop clickable, but she didn't appear there?! And defeating echo of Joy didn't seem to do anything but grant a fat load of money. I found shiny Misty once, defeated her, and that's the last I ever saw of her, even though I dumped loads of money into the book. Defeating her also didn't seem to do anything.
I guess some of that is just content not being made/finished yet, but it's kind of confusing and inconsistent.
Personally, I'd like to see the narrative being framed a little differently perhaps?! The whole shtick with the player character being some mute, unidentifiable nobody/anybody is kinda funny to begin with, but it gets kinda tiering. I'd prefer if the main character either was given some kind of set personality and design and actually interacted in the story, or if there was some rpg elements with dialogue trees etc.
Lastly, while the h-scenes are great, they're kinda poorly integrated with the rest of the game.. I mean from the dialogue of and the rest of the game, the tone is mostly the witty, kinda lewd, but not too much so style. The sex scenes comes kinda from nothing. Maybe integrate them better with some more dialogue or something to lead into them? I dunno. The whole ghost dick thing is also a little odd imo.
Anyways, I guess that all sounds kinda negative, but I really like the concept and the art of the game. Just some feedback. Best of luck, and looking forward to future updates!
