Alrighty, I've been playing this since about 2 hours after it was put up, and I love the heck out of it. I just got done exploring every possible route, which was a ton of fun to do, even if a bunch of the later stuff was in a rough state, i.e. unfinished animations and spelling/grammar errors. That's all to be expected though with a game still in development, so it's not too bad.
I did run into some issues with softlocks, namely in the scenes involving rain. Using the fast-forward feature would occasionally freeze the scene in place. I also think a scene selection would be a great quality of life feature, to make exploring every route less of a hassle.
I really like the dynamic all of the characters have (Jun is a sweetie) and understanding them and being able to relate to them helped make the dreadful section(s?) even more dreadful (in a good horror-y way). It definitely got my heart pounding! This was a ton of fun to go through, and I'd play the heck out of a more realized version.
Edit: Forgot to mention the visuals! Love em love em love em :)
Edit Again: Music's good too! ok
