Unfortunately, Traditional Chinese will no longer be in the final product of bugTDX. If there is a vocal playerbase who'd like that to change, I'd be more than happy to facilitate, however, it is quite difficult to debug the errors I have encountered setting up traditional Chinese.
Only ~1% of players on Steam have their primary language as Traditional Chinese, and it's likely I won't have any players who speak the language as I am marketing the game to a predominantly English-speaking market.
That being said, if you as an individual would like to be able to play bugTDX in Traditional Chinese, contact me on Twitter and I'll see what I can do!
