Terrafactor

The game currently has maybe 5 hours of content, and a huge grindy increase that is very hard to expand into thanks to many of it's combining systems. It relies heavily on the overworld for resource farming, and very limited use of a pretty rudimentary conveyor system for production. The mob spawn system is critical to understand for creating a functioning base, specially as it has "creeper" type mobs, but has no simple way to understand the limitations to protect/prevent mob spawns easily. So you create an almost entirely enclosed base, cover spawns as best you can, but you will almost invariably end up with mobs coming from somewhere, messing up your base and potentially exploding large portions of it. Which makes the game a frustrating grind to get what little land you can afford to expand into, while just hoping you covered it correctly.

Dangerously addicting, oddly satisfying. Genuinely well made game!
