No worries at all, It's impressive how you made this within a 4 day period and you can definitely see how much effort was put into the environment as it's one of the strongest parts of the game. Combined with the pretty but also dreary aesthetic that compliments the story.
I would definitely love to see a game with a similar aesthetic that is expanded on further in gameplay and narrative as you mentioned.
With how much time you had it's difficult to create something with an effective story or satisfying ending as a lot of gamejams usually struggle on that end. I think you had a decent story but with more time you can create something even better!
But overall I'm definitely excited for the future of what you can create. Whether it's a game similar or completely different from this. The ideas that you planted in this game make me hopeful as it's a game that has stuck with me after playing it!
Best Regards.
