"Failed to load" would imply either some kind of issue with either your download or the game startup...
We've been having a handful of reports in the past few days of curious error messages like yours, ones we've not seen before, that mention things failing to load or things being 'broken'. Not to deflect blame but... it SEEMS like itch.io's servers might be a little bit wonky lately and causing errors and corrupted file downloads, because we've never had any of these issues pop up before.
My best recommendation for you for now would be to redownload the game and try again. And to babysit the download and make sure it doesn't oddly pause or skip or anything in the process.
We'll look into it on our end and see if maybe something has somehow ended up being corrupted.
