I can clearly see that you project is a very early stage of development and has a lot to do. Nevertheless, I had some fun but I found some issues. I won't talk about assets and animations because it's not yours but I the idea of Matrix-style or Code Lyoko-style world is amazing. It looks very good!
Avatar, last Airbender - style game. I LOVE IT! It has a lot of potential with four main elements and their sub-elements. Main character and his master is an obvious reference to Zuko and uncle Iroh and that's a good thing. If you develop yours Zuko and Master right it can be a really engaging story to watch and play. I am impressed how you managed to hide UI, it;s clever and look very good. But sadly, Zuko doesn't uses his fire abilities but it doesn't matter that much. I just hope he will learn how to use it :)
My main issue is balancing. I found that you don't have to use any of the spells (I don't know hot to name it) and simply jumping through your enemies is enough to kill them. Other thing is that you can buffer (saves in memory inputs and later calls them in the fixed order) more than one attack in memory and game won't let you move because mc does his sick moves.
Pretty good but flawed game with room for improvements. Keep it going!
