Thank you! That's very detailed and kind feedback. We're very happy to hear all of this.
Regarding the art in some of the NSFW scenes, we totally agree with you. The thing is that the project has been in development for quite a while, and we made the first scenes a year ago. But all this time, we've been searching for a style that would allow us to make "juicy" scenes, but at the same time, produce and animate them quickly enough (we use Live2d, and this imposes certain limitations). As a result, we settled on the style you can see after defeating the elf monk. Now we will gradually update all the previous scenes - the next update will include a redesigned scene with Lillian (but so far, only the first one, where we meet her while searching for Grace's room. I'm sure some people didn't even realize it was Lillian because of the change in style that had occurred by the time the character appeared).
About the Journey mode, we totally understand that it's quite "flat" right now, and we're looking for ways to improve it. But there are only two of us - so we release "stages", gather feedback, improve based on it, release a new version, and so on, gradually moving forward.
We have now changed the concept of spells - they are no longer consumables. Now they form a separate spellbook, and they are used for AP in battle. We've also changed the leveling system - now they are separate trees of upgrades where you can unlock new spells or improve their effects/parameters by opening "skill nodes."
With the appearance of Olivia (the tailor from the new update) in our game, we now have an Atelier, which in future patches will allow us to introduce equipment to replace the current "upgrade HP to level 2" button.
Also, the system is designed with the possible presence of allies in mind. Currently, it's planned that you will be able to take students you have punished for misconduct with you (you remember how Harry and Ron were sent to the Forbidden Forest with Hagrid?).
In addition to this, I am currently busy implementing a dialogue system within the adventures so that some monsters/bosses can talk to you.
There are many ideas, it remains to implement all this, then check the reaction of the players, fix, improve, and then repeat.
Reviews like yours help us keep our spirits up and continue working hard, thanks again.
