Nice! I like the concept of the player having to decide which mode to be in depending on their current circumstance, however I feel like each mode could be expanded a bit e.g. Allowing healing during the storm mode, but attacks are slower.
The art is well done; each enemy has their own personality, which is also reflected in their attacks and movement patterns.
I feel like the general movement & combat could do with some tweaks to feel a bit tighter.
Well done on the submission! :)
