If you don't finish the game in one sitting, after you load a save, the next event or the next time you talk to someone you will only be able to see the text, and a black screen. I tried to play in my laptop as well and it happened again (0.2 version)
I just finished the 0.4 version in android, not in pc or laptop yet. Also once you finish the conversation or the event the game looks normal again. Im not sure if it is a problem of my own since no one said a thing about this, but im loving the game so far so I wanted to leave this here anyways.
