Thank you for playing and for the kind words <3
Indeed, I need to address some scene overlay weirdness. The next version will (hopefully) fix the last event of the day happening on the same tick as the evening event.
Either way, missing a scene is not the end of the world, the content menu is unlocked after the game has been completed or by going to About > Game content access. If the UI is messed up and you need to reload the save will bring you back to the start of the current day. No guarantee you will get the exact same events as before but eventually you will see the one you missed.
Augustine's message should arrive on day 2, then meeting her happens on day 3 but there is indeed no guarantee players will have read the actual message. I will play around with the delay/condition, things are this way so deleting the message does not lock you out of the whole storyline :p

In regard to audio, it is something I had put in the maybe one day basket.
I truly appreciate the proposition however I am also quite attached to keeping everything as a one person operation for a variety of reasons.
It wouldn't feel right asking you to work on a project for credit only (i.e. for free) or to offer some kind of revenue sharing arrangement for a game that has made a grand total of 0 cents and which I am not especially keen on making profitable (i.e. for free).
I hate to turn down such a nice proposition but I also enjoy the comfort of doing everything on my own, without the need for back and forth or anyone expecting anything.
You playing and enjoying the game is already extremely nice!
