It's not quite a ring, looks like a green glowing onion ring, and it's pulsating. What does it do?

Does anyone knows how to get this achievement? I'cant find any info on web....

why would you make a great game with no online coop or multiplayer? this actually does look like a good and fun game, but without being able to play with my friends around the world in online, i would never buy this..

I'm proud to proclaim, my brother Looplick and I now hold the new World Record in Voygage with a socre of 150,850 points! (170hrs of co-op)

I know this forum isn't super active, but I wanted to see if anyone else is having this issue. The game crashes any time I beat Odyssey or Voyage (I haven't tested the final mode). When I beat Odyssey I crashed, but I still earned the achievements and unlocked Voyage. However, when I beat Voyage, I kept the unlocks (including the silver cup) but I did not earn the achievements. I tried verifying the game files, and will report back here after I try again. Anyone else having this issue?...
