The new mechanics are awesome, travelling on the 'surface' is honestly fucking exhilarating and they've done a great job (though I wish they'd fix the bike so you don't get as easily knocked off, and they decrease the 'pickup' area on it so it's not as easy to pick up the bike when you get knocked off it whilst trying to run away from the worm.
I'm also loving the story so far too, but I won't get into it too much for super spoilers sake.
I'm also loving the night skybox too, I took this pretty early in;
(and yes I'm the kinda guy who beacons literally every biome and thing he finds moderately important, sue me)
overall, absolutely can't wait until the full release, twisty bridges biome best place for a base + table coral everywhere there, you're welcome.
also, feat me shitting my pants whilst in purple vents biome with my truck, I swam down to grab some materials, i turn to swim up and see this above my fucking truck. real divers know exactly what that fucker is
