Sorry! Rearrange the tiles so that every column is the same color and every row is the same shape :)
Thanks for pointing that out! The fix for that is now available on https://epiphane.itch.io/vessel (or https://gbjam9.nfshost.com/, where's it's updated regularly)
There was a file missing from the bundle uploaded to the jam, and submissions got locked so I put the real version at https://epiphane.itch.io/vessel :)
