The 2D RPG starter kit is a fun introduction to how games of this type work. That being said, this game could use a lot of improvements that would help to make it much more enjoyable and fluent of an experience.
One thing that would be very helpful to improving the game overall is very simple: make the scrolling of the text faster. One thing that severely breaks immersion is feeling that you're waiting forever for the text to load on the screen. Having auto scroll or faster text speed would remedy this.
Another thing that could help this would be to add diversity to the types of arrows. Having a bow is great, but in an RPG, it would be interesting to have a magical aspect to the bow. Arrows could shoot out fire, ice, poison, or even electricity. These special, higher damage-dealing arrow types could also trigger creativity for enemy types. There could be red monsters that are immune to fire, light blue monsters immune to ice, and so on. It would engage the player to try new things, and also force them to not just have dominant strategy, as you need to keep switching weapons up in certain areas.
Finally, character customization is a staple in many RPG's in this day and age. With this cute, cartoony art style, there is easily more incentive to want to characterize your person. Being able to change up the shirt, hair, eye and skin color of your character is a fun thing that adds a little bit of one's personality into the game, furthering the sense of immersion. You could also take a note from Starbound, a 2D RPG where you can choose 6 different races, each of which has their own unique flair, such as avian, robotic, human, and so on.
Overall, variety and fluency are the two main problems with the game, and the above suggestions should remedy that.
