Very cool! I'm also working on a Metroidvania type game so I love seeing other people's creations! I have a few comments/feedback.
-how come your main character has a sword if she doesn't use it?
-i like your fx animations! the smokes, fire and stuff looks cool! can't wait to see your character redesigns! What program are you using to create your art?
-i wonder if you can make A the jump button? maybe its just me but i found it difficult to use x to jump
-i think your control scheme on the game pad feels awkward. maybe it'll get easier when i fill up my abilities but I had a hard time pressing the correct buttons to do actions. I wanted to press R2 to attack to L2 is the default trigger attack. I kept pressing A (360 controller) to jump but it's X. this is definitely a bit nitpicky comment though in a way. Others probably didn't have the same experience with the controls.
I just got the double jump and will continue playing. Good stuff! So are you planning on having a map? What about an options screen? Anyway, keep up the good work!
