It's a stuff-up - the Host's Choice category ought to be host-voted only, but it looks like it is open to voters! Whoops! Hopefully Itch support will fix this...
Hopefully they can just exclude any votes that weren't the host's from that category. It wouldn't let me submit my ratings without choosing a score for that category so I disn't have a choice :(
In the worst case, maybe you can share your top ten or something here.
