Oh boy how do I start, this demo is so good that made me doubt that this is a fangame. I'm very surprised how well written this game.
I have a rollercoaster experience when playing demo. The Sun and Moon route is very creative and unique. I love how fleshed out MC's personality is having its own mind and character. Keep it up, it's really interesting to read.
I first played the Moon-Ren route and this route seriously made my heart beating. It was a strange experience how I able to interact Ren since he's a silent protagonist in the OG game. I'm baffled how adorable and smooth this guy is. In the sun route I'm kinda confused with the letter thing in the beginning so it's still haven't left an impression on me.
Ryuji route was cute, but well, the moon route is a bit weird though as someone who didn't know you well suddenly ask you to do stretching in someone else room. But who cares, I find it funny.
Akechi route had me rolling as the game gives you a trigger warning at the beginning. Well, what are you expected to date with this psychopath, amirite (¬‿¬)? That aside, his route is also interesting. Making a yandere story sometimes a hit or miss thing. But I'm having some high hopes for his route since it gives a good start imo.
Overall? Based from the demo, it's a good fangame. My favorite is Moon-Ren route (i love his playful peronality). No wonder this guy has a harem route in the og game. It'll be funny if his route suddenly has a harem thing and then game over.
Whoa, this is the longest review I ever write. Okay, I'll shut up lol
Sorry for my clunky english, I hope you guys being well and keep up the good work!
