The game is very interesting and I'm looking forward to how it goes after that, especially for those sexy sexy scenes. I'll also add the atmosphere is great. That said, there's a visible lack of polish:
1)There's a certain lack of responsiveness to what the player does: for exemple if you interact with your bed during the afternoon/night Elliot will comment he just woke, Emil is ALWAYS visible in the shower.
2)Some model's eyetracking just isn't there: Francesca and Emil are blankly staring in the distance where you get close to them.
3)There's the issue that there's options there for stuff that hasn't been implemented: buttons for the elevator to go places that can't be accessed, mechanics during the lesson that do nothing, etc. At least for the purposes of the first day, consider hiding those because they can be misconstrued for bugs.
4)The second ending screen where you refer to chapter 1 probably should be removed or replaced by info on the second chapter. Same goes for the initial message "I would advise not getting invested in this work" which uh... is probably superfluous.
5)There's a bug with the CG system where only the last CG used will be available if you quit the game and go back in.
Also please consider adding remapping keybinds. It 100% shouldn't be a priority but it's a nice QoL improvement.
