Very interesting game, haven't played much like it before. The art style is very nice, love the look of the stages and characters. Lighting and sound design gives it a very grungy atmosphere. The main character just having the yellow mask is simple but surprisingly works very well giving it a pretty iconic look. Combat was nice and taking out the enemies felt satisfying. It got pretty hard later on and wasn't sure how to get by no matter what different combos I tried. It would be nice to get some flashier cards sooner in progression.
The UI of the menu I think the glow hover effect needs to be better, around the entire words instead of just in the center background. The 'inearth' logo needs a thicker black border I think. The traversal I have to admit was disappointing. I wish you stayed on the actual stage and could explore around instead of going into this skill tree like map to go around stage to stage. I would much have preferred different doors at the end of the level where you can choose where to go and maybe even be surprised at what the path is instead of knowing it's combat next and such.
Overall it's really good so far, and looking forward to what is added next!
