I was playing this tonight and things were going alright. Unfortunately upon interacting with the dog the interaction froze. The background kept running, with the rain pouring down, but I couldn't interact with anything else or otherwise move around. I didn't do anything particularly out of the ordinary prior. It seemed to just hang there indefinitely - it was running in the background for a long time and still nothing changed.
It appears that there's no save mechanic either as far as I can tell. I'm running Windows 10 on 64 bit if that's of any help in tracking down the potential issue.
