Awesome expirience, tried to scoop every bit of the game as everything it allowed me to do. Backtracked a few times just to check for any interactions that I might have missed or which could have appeared...so I got a chuckle out of the interaction with the sister, oddly enough very clever way to tell to the players that "There is something to be done in the other house wing go explore the other way !" I hope it will continue to future episodes !
Now that I am done kissing your lovely bottom like Emil.
1) The already mentioned interaction of Emil in the bathroom playing each time you interact with the shower in any time of the day.
2) Notebook could be available from the start or lying on the desk, with Vivie suggesting to pick it up (I'm a dumdum who had to backtrack to classroom to take it)
2.5) Alternatively in the class room, the notebook could be just placed on the other end of the desk, closer to the player, so they have higher chance with interacting with it/
3) Also would be cool to be able to look up controls while in the game instead of having it just in the main menu. (I'm a dumdum who couldn't figure out how to pop up the notebook)
4) Not really a big deal or something of high importantce to put attention to, but would be neat to see the score next to each swimming level after beating it. Not something of high importance, just something to stroke player's ego a little bit, to see those SSS
Oh also you cheeky Box, giving me a scare in the easteregg location ! Loved every bit of it.
I have huge hope to see another episode !
