The drawings on the top and bottom borders are so cute! I also like playing choose-your-own adventure type games, so this was pretty fun to play. :) I never thought I would see "high school anime fish" in one sentence haha.
One critique I can give is that the purple part of the text blends in a little with the background, so maybe make it a little brighter? So there's more contrast between the text and the background to make it easier to read, since the game is all text. I do like the gradient effect on the it, though. This is a great job for your first game! :D Congrats!
