I'd really love to actually try play the game if you could upload the whole Unity folder as a zip? Just make a new project upload and I'll check it out. In any case:
You say you messed up because the game is "based off dialogue and graphics when I know nothing of the sorts" -- you seem to be falsely assuming that you can't start a thing until you're good at it. A very backwards idea. How else are you supposed to get good at doing writing and art for games if you don't do writing and art for games?
I suspect that you were very happy with your concept of a game, that you had a grand, perfect vision for what it was going to be. Your disappointment, then, comes from the disparity between what you thought you were going to make, and what you actually were able to make. Maybe you feel foolish, and it seems natural to beat yourself up, but be careful: don't beat yourself up for your lack of ability (it is okay to still be learning), what you need to challenge is the expectations/standards you hold for yourself. So long as you hold youself to such an impossibly high standard, you're doomed to let every genuinely helpful learner project be a gut-punch to your esteem. It's like cursing yourself out for successfully playing piano scales because you're not playing solfeggio in C minor.
Basically, if I'm not able to play your game for more specific helpful feedback, a word of advice: make simple, tiny games, and work to polish them a bunch. Even allow them to be bad, and know that it says nothing about you.
If you perceive this stepping-stone as a pothole, as you seem to be doing, that is actually what will be 'messing up'.
