I let out the deepest, loudest groan of despair and agony when the game stopped as I was going to the park. I want MORE! The art and the unique UI feels VERY PREMIUM and the plot (while a little generic) has a really special feel to it. The characters for me are the most interesting part, especially the sister. The fuckin thumbnails made me so excited for that scene with the sister ( you tease >:[ )
The dialogue is great! It feels natural and flows well, environment art is top notch, im usually a hard critique when it comes to the comedy but the humor in this one, i'll let it pass lol. And while i've said this before, the UI is certainly one of, if not, the best i've seen in any VN. For me, making a great UI isn't a hard thing to accomplish with a great imagination but you've done it, bravo.
The only criticisms i can give are:
-The Tutorial. I really liked the concept, it is slick and smooth. However, the tools become really hard to see, and for casual, clicky VN players like me, you tend to miss a bit of tools and how they work. I would suggest arrows, more highlighting, or even scaling it up for a second for the player to notice easily.
-The Hidden Money. I didn't really like that mini-system, it gets really tiring for a while clicking everywhere on the screen in hopes of getting free money. The best you can do with it is to tweak it so that the money is actually visible and you'd actually have to use your eyes to get them, doesn't matter if the art is small or not, just make it be that there is a visual advantage.
-The MC's look. This is more of a personal critic for me but i was hoping you could make the MC stand out more. He looks really plain and generic and it kind of bothers me. It's up to you though, no pressure.
Great game solid 9/10, I literally cannot wait for more. I am at the point of refreshing this page everyday for updates :P
