The writing that I have come to expect of you.
The impact of your choices feel real, and the conversations aren't about picking out the corny 12 years olds concept of romantic pickup lines as the VN genre tends to force you to. Corny lines are met with the response that they would in the real world, and instead it's much more about trying to make a real connection with the romantic interests through regular conversations. There's also plenty of well written humor to go around. Honestly, this wouldn't even need to have sex scenes for me to enjoy it at all, although it does add an undeniable intensity to the romantic aspects of the game, which is certainly a positive thing, but it still stands to show how much I actually enjoy the writing. With the slice of life genre being oversaturated with pandering escapist moe-fluff and monotone 1-dimensional archetype characters, I usually despise the genre, but as with Crusoe, this had me glued to me screen for around 5 uninterupted hours. A very immersive experience that actually had me caring about the characters.
I hope that you will make more of of these character driven games in the future. Your writing is amongst the best that I've seen in the VN industry, and I really hope you continue to focus on this as your primary asset.
