Top tier visuals, and tbh completed it on my first try, so not too hard.
Some areas of improvement:
- I feel like the boss is a little too grindy and repeats the same patterns too many times.
- Lacks effects, like dealing damage to the boss, when it change states etc. (here's a good shader for unity to make enemies flash white https://answers.unity.com/questions/1074261/make-a-sprite-blink-white-when-hit.html )
- Also I would recommend that you add screenshots / gif / gameplay video on your itch page.
