You know what... I really like this game! My first impressions were already really good from what I remember and after trying newest update I am happy to see the trajectory hasn't changed. Maybe this games doesn't have the best character designs, most innovative plot or abundance of sex scenes or visuals in general, but what this game does have - a really great relationship that feels genuine, but isn't afraid to be playful, teasing, romantic with a touch of naughty. And while same can be said by some other games, especially in this phone game era, I usually dread parts of the conversations with excessive points of insecurity, anxiety, reassurances. Here the conversations have a certain flow to them, my attention was kept all the way through and I feel myself being attached to Mina, I care for her in a variety of ways. Honestly other characters are great to converse with as well, so props to writing on this one! Not sure about Blue yet, need more advancement, I am a bit scared I might not like this part of the game, scared this is where the fumble happens, but I could be totally wrong. Oh and last but not least, I don't know how much choices actually do stats and routes wise, but I find that they are well placed with good responses and sometimes I even struggle to choose, but this is not a frustrating experience more like they are so nice I wanna pick both at times. Personally, I really hope that actual sexual contact with other girls for MC will always be optional, but that won't block you from enjoying nice visuals. I am a big fan of look, but don't touch. Only Mina gets to have MC, deal? haha...
Sorry for long post, wanted to drop my thoughts while they are fresh. TL;DR - good start, keep it up, and good luck!
P.S I have huge respect for devs who shape their own style and work with what they got instead of trying to find some complicated things. So when I, or maybe others, say something about visuals not being best quality or something looking weird or something feeling like it's seen before. Please ignore that noise, focus on actually finishing the game which is so bloody rare these days. After that is done there is room for polishing updates or even DLC's so to speak, or maybe better yet another great project to apply stuff learned in the first one. And sometimes things that are weird at first grow on players and then it just turns into this unique recognizable style which helps people put this game in memory for a long time and stand out. Oh and don't get lost in the animation/rework/steam sauce.... there lies the real PTSD for me.
