Came back from the death to answer, you can use either audacity to convert the files to OGG or with this link https://www.online-convert.com/ however that converter sometimes affects the audio quality. The font I think it's "Belleza"
Well, I don't have any knowledge about music theory, it's mostly playing with sliders till it sounds good, so I'd feel kinda bad for asking money for something made like that. and my goal was to make resources that developers could easily grab to get their ideas or prototypes done without any worry, that's also why I don't ask for credit.
the font is not mine it is was an Itchio page option to change the font, but you can download it from google fonts https://fonts.google.com/specimen/Amaranth?query=amara (I think their fonts are free to use, but better check their policies first)
I'm not a lich.... yet... it's just that due to homework and my computer dying twice per month that I haven't been doing more resources or anything related to game dev so I kinda forgot about itchio.
