Hi nice entry :) with very charming handmade art, it would be great to see that as a consistent style throughout.
Story wise it was nice, it seemed like you were setting up a vast and interesting world and there is a lot you can build off from this entry. Including with the characters not just having thier different elements but different personalities as well :)
Gameplay wise I thought the chests were nicely spread out to promote the player getting away from the obvious path to explore the maps a bit. The battles were straightforward but focusing on the rock paper scissor formula with the elements fit well with the world you were setting up. I did find myself escaping a good portion of the small battes as the non-boss battles were a tad bit long for me personally when considering the presented mechanics. While others may appreciate the longer battles, I did like that you provided options to alter the battle frequency or escape without penalty.
Thumbs up, and congrats on the submission!
