Thanks for the detailed review, I appreciate that!
Yes, I had most of the things in mind as well. I wanted to track enemies that are close to the player and give the characters an option to target those. Also I thought about buffs, depending on the staff you are using. But I didn't work on it in the time. There's surely a huge amount of stuff that could be added within such a RPG system - I actually consider to make this into a larger game at some point. :)
For music I also didn't have the time. I wanted more SFX, footsteps for example could have given it a better feel to walk.
And yes, unfortunately it doesn't look very Gameboy-ish, I expect to get a bad result in this category. I just wasn't too sure how to do it, I guess having everything as sprite animations would have made it alot better. I keep that in mind for GBjam9 :)
Thank you!
