The game is absolutely not worth playing at the current stage of development. It does a good job looking like it has content, but it actually has almost nothing. Current version ends with 2 intro quests completed out of total 15 and the rest is "locked" which means you start them, you do one or two initial stages and end up finding out that you can't progress past that. For the princess training which is what this game is claiming to be, there is only inspection scene and face moisturizing ending with exposing tits and you can only train exposure comfort, filth tolerance and maybe lower her confidence, but none of these stats matter, as they unlock nothing. There is also a dildo blowjob tryout but if you try to repeat that she complains she needs a smaller one to train and you can't get a smaller one, that's it, single stats here and there.
As for the fragrant slimes I think it was the purple slimes, first you go the left area where you use the grappling hook, enter first door of three, go next area, one of the guys will have a key and you can go inside the locked area with purple people and purple slimes.
