I downloaded Hammer recently and it's safe to say that I loved it, though Ihaven't seen any recent update, not even from 2024.
Is the game closed? Or the developer too occupied to even continue it?

Still here. Just working on a new mapgen for branching missions. That's all.

It's going a bit slow because I went back to Warframe to get more inspiration about the mapgen and mission types and ended up getting sucked in lol.
