Interesting in the way that characters speak and think(MC) in a way that sounds like you're having a conversation with someone or would have those thoughts pop into your head in reality as the reader. It really helps in immersing yourself while reading when the dialogue and inner thoughts seem natural.
I personally also found the numerous choices rather thought-provoking - texting choices especially. On top of leading me to consider how people communicate with one another, it also emulates what I would think to be a very realistic situation - agonizing over what message to send to a girl you like, even if it would appear completely inconsequential to an outsider. Being able to understand the nuances of texting conversation and then properly conveying them while simultaneously offering agency over it implies that the author has an impressive in-depth knowledge on what they are writing about. Because there are so many opportunities to decide what to say specifically, it truly immerses the reader in the neurotic mindset of the story's protagonist - this further reinforces my impression that the author either has done some deep research for the sake of realism, is able to write what they think this kind of character would say or think straight from their own imagination(!), or is writing from their own personal experience - which would truly make this something worth reading in my opinion. (My bets are on the lattermost) This really leads me to get the impression the creator has thought a lot about his characters. Even though there may only be two, these two characters are intended to have profoundly more depth than what you'd normally come across in similar games in this vein.
I think that most people would not give it a second thought, but the animations that were added to the game also give it a distinctive flair. I've found that similar type games are almost completely barebone plotwise and just rush to the H-scenes. This game is focusing on the actual character interactions beforehand and it was easy for me to tell the author is trying to make something they actually want to make right when that drinking animation started playing. Things like these are normally not even considered in similar type games from my observations and because the author took the time to make multiple smooth animations, it is crystal clear to me that they are not making this game just for a quick buck, but to learn and create something to be proud of. (Especially after reading the about me - I get the impression all of the more technical skills were learned from the ground up)
The game may short, but I like to think I can see the intent behind it rather well. There's already so much to say at v0.3 that when this is released as a final product I'm sure it will be a masterpiece. I'm hoping for full voicing.
