Here's another one - pressing the "back" button on the diary screen unceremoniously dumps you to the title screen. Did this twice now: (
Also, the game's video refresh froze when I left it sitting with a dialogue open for about half an hour (it was the "Why is the portrait upside down?" one on the third day.) I could still hear the audio of the text output playing, and I could hear myself advancing dialogue, but the screen stayed frozen.
I seem to be experiencing all sorts of bugs, and so far haven't been able to progress past day 4 despite trying about 5-6 times.
