Yeah, this was my experience as well. The adventure aspect really doesn't add anything to the game, other than doubling the runtime without improving the story or the characters. I also accidentally closed the button with Esc at some point. I just gave up and watched the ending on YouTube isntead. ¯\_(ツ)_/¯
I really wish the story and characters were more fleshed out, half the side characters we're just stereotypical stock characters and didn't feel like real people to me. And the horror of Parsnip being a psycho just... isn't interesting or suprising. Like it feels like the only thing this game excels at is the cute factor and the character animations. Everything else just feels incomplete to me.
The game also really sorely needs a skip dialogue option. There were 5-10 times where I accidentally started talking to the same character twice and I just had to sit there for 10-20 seconds before being allowed to move on.
