Hi, guys
I've finished level 20. The gameplay is actually quite boring, but I'm persistent!
The developer is focused on his dress story, so that's the key to progressing through the game.
At 7 a.m. and 6 p.m. (the clock doesn't advance), you have to go to the workshop and choose the dresses in order, one after the other. Then, don't forget to stop by Théa's room to confirm your choice. Never force it, it doesn't work.
Then, at 7 p.m., spy Théa changing, and you'll see her take the dress you've chosen.
At 6 p.m., in the kitchen, go through all the proposed options to advance the counter, likewise in front of the TV (romantic, erotic, horror). Don't waste your time on pool, evening and beach stories: as soon as they're wrapped up, fairly quickly, drop them.
By doing so, you'll make slow but sure progress. Enjoy!
