Some thoughts I had while trying it out:

Cool minimal visual style and movement feels solid as fuck, really ponderous and heavy

Really bad lag when mining but damn, it has terrain deformation

Can't really tell if the game's gonna be more action oriented or need careful maneuvering and precise mining - movement says simulation, carving away huge chunks feels pretty actiony.

I kinda wish I could physically drag around those asteroid pieces with a tether or something after I've cut them to manageable size - like Lunar Lander with mining or something

Shitloads of potential, I like it.

Really reminds me of the first Gravity Well.

I like it.
