To put an even finer point on it, no, @AdmirableAnimation, I’m pretty sure a link to your Ko-Fi would not be permitted. That counts as a donation, same as a Paypal link or some other way to donate, which is not permitted unless you obtain/pay for a license to use ChoiceScript and give COG 25% of your earnings:
You can also publish your game for free , anywhere, and do not need permission to do so. However, should you intend or hope to earn revenue from your game by any means other than publishing via Choice of Games LLC, you must obtain a license from them authorizing you to use ChoiceScript for this purpose. Typically, this will cost 25% of all monies earned, including income from sales, advertising, sponsorship and/or donations in any way or form connected with the game itself (including, for example, advertising or donate buttons displayed on the same website as a ‘free’ game link).
From the FAQ:
Q) Do I have to pay you a fee for the code?
A) As long as you don’t make any money off the code, you don’t have to pay us anything.Q) Can I host a game on my own website?
A) Yes!Q) What if there’s a “Donate” button on the webpage with the game?
A) That falls under the phrase “making money”.
I’m pretty sure a Ko-Fi link is the same as a Donate button in essence; but keep in mind, I’m just a mod and not a staff member of the company!
