Welcome adventurers to my wonderful puzzle! I hope you enjoy! If you need a hint: Qiesa lew axelnvkws. Of course, you'll need to decipher that if it's going to be of much help! You will need a LOT of resources. Feel free to use AI (not that it'll be much help here) :). Also looking at the code/costumes is not going to be helpful, so don't even try that. Because you can access the code, I need you to comment your answer instead. I'll probably let you know whether you got it wrong within the next month.
I got the idea from a website. For reasons I can't explain without giving the answer, I am unfortunately forced to withhold such knowledge.
