Hey,
love the rpg so far :).

for a future version, how about

class specific items / spells
event triggers (on reaching certain levels, there is a trigger (storyline, new item)
ability to hold more than one potion or item
less power difference between levels (level 2 isn't 100x better than level 1)
rpg chat - Like, shows your rpg character's image, and a little text bubble coming out of it. haha


Just throwing ideas out there
