First, it took me a bit to figure out how leveling worked, since I don't remember it being explained in the tutorial what was the game's version of experience and I didn't see an experience bar. Second, once I did figure out that IMG = experience, I didn't know how much I needed to level though I eventually found that under the picture. It's great that leveling refills our energy bar, except that its frequently wasted because I'll level when I'm at full because there's no easy way to track your leveling progress. There needs ot be some sort of IMG/level progress bar or meter like there is for energy and mood.
