Ah, I think from an aesthetic perspective your artist probably made the right call on the wording for Kong Jr., given that he was planning to use the Chinese characters. The "more correct" wording (in Chinese, at least) involves fewer characters and fewer strokes, and probably most of your players aren't going to be actually reading it anyway. I'm honestly barely literate so it was partly the novelty of being able to understand the characters in the first place that even made me notice the phrasing xD
Also yeah, I can definitely see how the time constraints of the game jam would interfere with your vision for the theme that way! I hope if you revisit this game in the future, you get to add the evolutions and abilities you'd planned on :)
