I really enjoyed this game! Every level felt like a mini Metroidvania. All of the powers were nice and gave me some serious Avatar the Last Airbender vibes too. Very nice game!
If you wanted to improve, I suggest giving each element both an attack and a defensive ability. This would open up gameplay a lot more with enemies that take more damage from a specific element and less from others. Some sort of collatable coin or hidden lore would also help to encourage the player to explore more.
Overall, fun game!
