Thank you for your feedback! I have been working on an update to increase the quality of various things in the game. I will post about it soon. (EDIT: The post is now up.) I am still working on this update, but I will keep your feedback in mind to improve some of the things you criticized.
Can you please explain what you mean by the writing being "juvenile?" I do enjoy writing for kids, and although I originally envisioned this game being for general audiences, I guess I wound up leaning more towards kids as my audience. I haven't spent much time on this website, but it does seem like most of the games (at least the RPG Maker games) are more serious and adult-oriented. Is that what you mean? I wonder if there's a better (by which I mean more fitting) platform for indie kids' games...
No item was equippable? That's strange. I specifically set every item type used to be equippable by every class in the Database, and I'm pretty sure I was able to equip them when I tested the game. Maybe it didn't save. :P I'll have to take a look at that.
It looks like I'll have to buff the boss and/or nerf the power of the normal attack move. Buffing the boss will be easy, but setting stats for the playable characters has been difficult for me. Please bear with me as I try to figure it out.
Thanks!
