I died at least 3 times immediately bumping into the strongest enemy in the game (at least from what I've seen), otherwise I wandered around aimlessly until I found a weak enough enemy. To solve both problems, I'd suggest adding some kind of arrow/obj that keeps sending you towards an enemy approximately your level (total sum of the currencies you've collected so far?), with the game becoming bounty hunting these guys while avoiding "the bigger fish".
The idea and visuals are quite nice however and there's absolutely nothing to complain about. All in all, great effort!
