Thank you so much for playing and for your in-depth review! I'm sorry about how broken the main menus are, at the title screen and main menu—that was something I shipped knowing was broken because I didn't have time to fix it. All of your critiques are great ones. If I ever release a new version, sound effects and more music are definitely something I will add. Music really is everything in creating that atmosphere which is why I'm so happy I was able to use crxw's music for parts of the game. The door creaking in particular (as well as footsteps when Sven changes rooms) was something I thought I should've added as I compiled the game. On the save/load part, I do the same whenever I play VNs, and the decision to just remove saving entirely was a conscious decision because I wanted you to play the whole game in one run without going back. (I forgot to get rid of renpy's built-in rewind though, so this actually just ended up being mostly pointless). You should be able to press continue after beating the game to see all the ending choices though. Not that they lead to very different outcomes. This is my first ever game jam so I ended up not pacing myself particularly well. Every line of code and piece of dialogue was written on the last day of the game jam because I spent so much time with the graphics and broadcasts. I think that also led to the ending being less satisfying and scary than I wanted.
Thanks again for your post, nin. I'm glad the game scared you :)
