Cool game! I really like the art style here. The animation on the angel character is really cool and I love the stylized look of it. I think the concept is really cool and there is a lot of unique ideas to be found in this game. One thing I think could be improved is the tutorial at the beginning. I think having some kind of visual reference for the mechanics you are explaining could go a long way. I also think having a "charge bar," or whatever you wanna call it, for the amount of lights you have could help to clarify that to the player.
Thanks for making this!
