My comment on the story isn't specific, it's about the whole plot lines and the tone of the story. Collect stars, enemies become friends, the protagonist is a hidden gem... I mean can't we get a subversion maybe? Maybe an original plotline? An interesting twist? Or at least keep just 1 trope and develop it more considering the time you have to make the game, at least it won't feel so rushed. Alternatively, use a different tone like a Shakespearean tone, or down on your luck, or something strange, unexpected, or different.
Anyway, I'm sorry you don't feel my feedback is not helpful, I did mention the lack of depth, if you had time constraints just try reducing the scope and prioritizing things. I suggested turning it into a comedy then you can make fun of any problems you might have, suggested you add branching narratives (so choices matter), suggested boosts, traps, enemies, and items, any of them could enhance gameplay. Finally, I suggested a race if you want to go for the pressure route, which could also make the experience more interesting.
If none of it gives you something concrete to make real improvements then I'm sorry, I tried.
