Nice color scheme choice! It complements the character design and power theme well.
We like a lot of the concepts around this - controlling smoke and then later on merging with it for more direct combat. Feels magical girly with it's two forms!
We'd like to see a bit more polish on environmental hit boxes and level design. Currently there's a lot of waiting which isn't that engaging, and some of the timing based rising platforms could use a bit more forgivness on the jumps.
It would also be nice if it was possible to punch while moving.
Overall a nice concept, good job!
