Wow I spent way too long on this game farming those shinies (Not sure why you called them that made me think there were shiny versions of pokemon), This game is brilliant the little conversations and defeat messages add nicely to the personalities of each character even the receptionist gets some character development. Combat is solid and feels fair and I like how the player progresses through the rooms. The henti scenes are nicely drawn and now have animations after a bit more work (Maybe add a way to get animations for the Echo versions too?) Even after you can't progress anymore there are still hentai scenes the creators snuck in and while I spent a ton of time farming all of them I could only get Eevee and Nurse Joy's hentai scene. But I think Jessi and Braixen are also possible since they aren't echo's unlike Misty. Almost got to Lv 100 farming the hell out of them. If I knew hat it's possible to get hentai scenes for them I'd definitely still be trying.
If I could suggest one thing maybe after you've unlocked all the stickers you could make it so the gacha machine malfunctions and swaps all your sticker tokens for extra stickers since clicking the normal gatcha 100+ times doesn't seem very practical and the gacha has no use at that point other then extra stickers.
Can't wait for the next version I'll definitely give your parteon a visit, Such high quality content needs to be supported. Thank you for this game.
