I'm really nostalgic for that period in the mid 2000s when I was a teenager making silly games with RPG Maker (...XP) with no care in the world, and this is clearly a game made with that spirit! So just for that you have a thumb up, but a really subjective one.
The writing is juvenile at best but the characters are really intertaining! I actually liked all of them! they were characterized and fun enough, even for such a small time! This is actually an achievement!
The art for the most part, is promising. not going to tell you "great" because it's not, but there are some drawings that show promise, and you should keep practicing!
Now, if you'll ever consider game development on a professional level, I'll give you some ***Constructive Criticism*** to help you improve!
- The average player doesn't care of how confident or not-confident you feel about your skill with the RPG Maker. This means that all the "I didn't make this asset" jokes (like the dragon and the chichen) and the joke about the design of the shop map will only land on other RPG Maker devs with similar skills to yours. (The chichen "shut up" was a lot of fun though)
- Similarly, the averege player doesn't forgive your lack of knowledge of RPG Maker. This means and all the "please don't break my game" requests (like "don't recruit people too soon or you can't solve the puzzle") will irritate him and communicate a lot of amateur. (I did something similar once, so I related!)
- The combat makes no sense: the boss brings no challenge and I beat with a few items and no equips. I didn't equip anything because no item was equippable.
- You should guide the player somehow in buying the proper items because he doesn't know what the fight will need and how to spend its money!
- The spells make no sense. I don't mean "story-wise" but "gameplay-wise": why should I rely to a spell that costs me mana to just damage of an amount comparable to a simple attack?
- I know for a fact (at least on XP it was possible) that you could set up events during a fight, like dialogs. Since the boss has too much health you should set up some dialogs to hint the player she's going down!
Hope I helped! Overall I had a nice time playing! Keep going! ;)
