Wow, that's really hard. The best score I got was 2. It took me a while to figure it out (you have to push the food away), and once I did it was just super hard; there's a ton of stuff to deflect and getting the angle right is super finicky. I think, though, for a "so bad it's good" game it works. The whole thing is bizarre and the total lack of context actually enhances the weirdness.
The first time I tried the game the spacebar just moved the page down and didn't register, but it worked the second time. No idea why this is happening.
