UX Thoughts after reading the design brief:
1/ Arrange Upgrade btn in the middle, which is convenient for operation in the most comfortable place for fingers
2/ Skill need to be relocated, 1up 3down emphasizes a basic natural ability was given. The rest is empowered based on that one.
3/ Need to explain the logic of Shards-Unlock Skill-Mini Star up
4/ Few materials so far, worried about there is no place to display skill descriptions. How to make a quick and linear judgment?
5/ Trailing animation is necessary
6/ Need to combine blind boxes/toys/increase youthful fashion/mystery feeling
7/ The interaction details need to be more unique and unconventional
