In all honesty, there's a lot of room for improvement. The dialogue, conveying the story, consistency, expressions & atmosphere (pretty lifeless right now, feels kinda empty), and there's a lot of confusion that needs clearing up. Choices are also a bit strange.. MC likes X person, but keeps going against the flow. Gets attention, turns the tables. And this can be further amplified by the player choices.. ?
Jenny on the other hand has too ambiguous character. Treats the MC pretty poorly and is clearly not interested in anything romantical. Then she's interested in her father. Then out of the blue, she becomes very interested in MC and while she's normally "free-spirited" and does whatever she wants, she suddenly shifts to being insecure and borderline shy. As for the trash-bin thing.. I don't have any clue what that is about and can't really say that I want to know either. It just feels like unintentionally comical and kinda weird.
Backstory is nearly non-existent, but there's a seemingly important plot (which seems okay so far). There's some suspense around the plot and I think that's a good thing, but it could use a bit of polishing.
I realize that all of this may sound harsh, but it's not my intention to degrade your work. I can't say that I like the game, but I do appreciate the effort and that's why I'm trying to point out the areas that (in my opinion) need to be improved.
I would say that planning is a very important aspect when creating a game, and consistency across all areas is a close second. Adding some elements that can capture people's attention would be nice. Same goes for the ability for people to relate to the story (very hard to do at this stage), and invoking interest & caring about characters. They're too generic and a bit stale at the moment so I doubt that a lot of people find them likeable.
In all fairness, creating a game takes a lot of work. Creating a good one takes even more. Don't rush it if you're aiming for quality content. One step at the time. Give each element it's due attention and your work will improve monumentally.
These are just my thoughts on the subject, and some advice that's meant to be constructive. I would suggest starting with building each character's personality a bit more so that they stand out, but that's just me.
Either way, keep learning and don't give up. Best of luck!
