I get your point, but there are some pretty specific similarities, notably:
- Grass texture sides having exposed dirt
- Clumps of pumpkin blocks as a forest-generating feature
- Single-block tree trunks with a clump of leaves on top
- Minecraft-like terrain generation and texturing
All of which are featured prominently in the screenshot. There are differences-- taller trees, more small vegetation, different grass block color variation, colored and differently-modeled leaves-- but it's more similar than other voxel-based games I'm familiar with. Maybe I don't play many mc-likes, but other voxel games like Fractal Block World, Teardown, that foresty one with the tiny voxels (forgot the name), Lucid Blocks (the other voxel game by this same creator(!!) about a liminal world), and even Hypixel have more notable differences than this screenshot does. Maybe there's more to the game that's different, but this particular screenshot looks like lightly modded MC.
