It took me almost 10 hours to explore it all, and most of that time was pleasant.
You get teleported into a Magical Camp, where only women are allowed, and you can't get caught, because the director has a horrible relationship with men, and she usually transforms them into frogs.
So, if one day you'd like to come back home, for now, you have to be disguised as a woman.
The fact is, that whole universe is committed to transforming you, piece by piece.
There are not many graphics, so many transformations are mentioned in the text, but in a well-done way, spread across the whole story, that's not over yet.
There are both physical (up to basically completely female) and mental transformation.
If you intend to play it, consider that you can't just skip dialogues, because there are many puzzles and you need those instructions to go on (the Q shortcut allows you to read previous dialogues). But, if you want to skip, you can do that with the CTRL shortcut. You can also run, holding SHIFT. To play it fullscreen, you need to right-click the window bar and select it. And don't forget to choose the easy mode (it's already hard), and to turn off standard mobs into the dungeons (only doable now with the debug switch, that will be removed): they don't give you anything else than money you don't need, but they require a lot of time.
That's because, in general, the fights pokemon-style fill a long part of the gameplay. They can actually be nice, because they're well-thought if you like them, but I'm very happy I skipped the usual mobs.
You'll probably need the wiki to figure out many things. DO NOT fight the bosses before saving the characters, otherwise you could miss some important parts of the story. And save often, because there are many bad endings, and you'd have to restart all over if you had not saved before.
