I feel like the biomes from the shallows to the thermal vents to the purple mushroom biome at the start are all very similar in depth and in creature variation. They all seem like they are at the same depth basically all from 0-150 meters. seem like you see the same creatures in all of those biomes until you go to the alien ruins area. Would like some more depth and uniqueness with these biomes with maybe some deeper caves that are isolated or a biome under another biome with a unique way to get there.
