To be honest, just the opening situation already started to make me feel breathless...
The atmosphere is incredibly oppressive and real. It perfectly captures that specific anxiety of being with a difficult family member. The immersion was instant.
That's why it was such a shame when I hit a bug on the Web version where the game wouldn't transition to the choice selection phase (I was unable to click any options), so I couldn't progress. I was so invested in that suffocating feeling and really wanted to see the end!
