Here’s Heal the Bay’s page on SurfGod HtB!
There’s a visual issue in the current version of SurfGod. The secret character is not unlocked with a score of 4000+ — you unlock this avatar as indicated in the ‘i’ screen. This is the constraint for the “SurfGod HtB” special character. Making this fix and there also is apparently some issues with the achievements totem..we are fixing that as well!
