I really like the art style of this, especially the clouds. The music and the text made me feel like I was playing "Hand of Fate" (a comparison which is intended to be praise)
I was unsure how to perform the combos mentioned on the itch page or if I was preforming them successfully; maybe some UI element or sound effect variation would help communicate what's happening with that.
I got comparable success both actively playing the game and just watching it run without my input which seems a shame. Is there a specific pattern to each enemy that I could learn or some telegraphing they could do to indicate their next attack type? I didn't feel like I was making an informed decision when picking my attack.
I really liked the use of the theme and the detailing on the environment and boxes. I appreciate the cohesion in using the little cross on the boxes as the timer indicator too!
