It is really hard to figure out what is going on with the elements combined.
Game needs some more onboarding on that. Also it should be some fun way to find out the elemental weakness of the enemy and than player should have the way to make it hit harder or something :)
I really love your idea, and combine mechanics, art and music. Im also impressed because you had to make it in 48 hours!
I would like to play some more, but right now it is too hard for me.
