Through my playthrough, i struggled to tell if the area i was in was part of one biome or another. I feel like the transitions are mid and could be better since most areas feel like another biome but with a reskin. The transitions could be better

Take a second and look at these biomes: Anemone Hills, Graveyard, Bleached Corals, Hot Caves, Coral Gardens, Observatory, Metal Farms, Plateaus.
I feel like there’s a huge difference.

they are different enough i think but the blending could really get improved and i think it should be a bit more distance between the biomes. I think the graveyard is especially badly blended it just feels out of place and is a bit immersion breaking. The biomes themselves are very good though although currently they are a bit to bright and lively i would like to see scary grey couloured biomes.
