As simple and short as this is, it was fun playing all the way to the end of the game!
Other users have already given you a lot of great suggestions for you to improve on your future game-development endeavors on RPG Maker, in particular.
That being said, I have only one advice to you: Don't be afraid to explore new grounds and try new things! Always keep on improving! Perhaps one day we might be granted with a great game from you in the likes of other great games like the Final Fantasy series if you don't ever give up!
