Thank you very much! :)
I used a scripting language called AutoHotKey, which is absolutely not normally meant for making games, but I just wanted to use it this time specifically for the fourth-wall-breaking stuff it would allow. :) It might have been possible with other languages/engines too for all I know, but I wasn't experienced enough at doing anything like that with other languages or game engines to know for sure, which is why I decided to use this one, and hoped it would work out!
