@DleanJeans Thanks again for the help. I had run across mention of Nape on a few forums, but was not familiar with it and did not realize it was what I was looking for. Hopefully these will steer me in the right direction at least.
Sorry, forgot to specify which platform I was targeting!
I replaced the .mp3 files for .ogg ones, but the game still crashes upon opening the neko binary, now with the following error:
export/windows/neko/haxe/ApplicationMain.hx:205: characters 57-75 : Warning : Use programPath instead
export/windows/neko/haxe/ApplicationMain.hx:80: characters 47-65 : Warning : Use programPath instead

I'm not too familiar with github but I'll try to open an issue.
