The first time I loaded it, the game faded out as soon as a level loaded, but let me move onto the next level regardless. All subsequent attempts have had no music and don't move me to the next level when I get the checkpoint. I'm seeing a null reference at SnailTrail.framework.js:10:36614, and a warning about two FS.syncfs operations at once in SnailTrail.loader.js:1:1309
