Ok, I need feedback from all 2 of you people that read this.
In GBA Anguna, you were motivated to fight enemies as you explored the overworld, because they dropped money, and you needed money.
In Atari Anguna, there's no money. I just don't have the ROM space for shops. I'm toying with the idea of replacing it with experience/level-ups. You get enough experience, your max HP goes up a level.
The advantage is that it motivates you to fight your way through the overworld instead of just running past everything.
The disadvantage is that it encourages/allows grinding, which I hate.
