Horiforge

That's a fair question!
Horiforge is a different kind of experience from what you may be used to. There are no traditional objectives to complete: the gameplay is built around exploration and discovery, rather than overcoming challenges or progressing through some missions.

The experience are the worlds themselves. As you travel across them, you will come across increasingly strange and unusual things that react to your presence, and the further you go, the more diverse they will get. Any ordinary walk can lead to unexpected discoveries that are truly unique for your playthrough.

Think of it less as a game that tries to entertain you by telling what to do, and more as a universe you get to experience.

If you're looking for clear objectives or constant action, Horiforge probably isn't what you're looking for. And that's perfectly fine! But if you're open to slowing down and exploring the universe simply for the experience of being in it, or you are about to create something and need an inspiration, you might find something special here.
Or you might not. Depending on which portal you choose, hehehe.

Cheat codes are another nod to retro games, as well as a cool way to include easter eggs. Where do you get them? The internet I guess. One of the first Steam testers cracked them in like 0.2 seconds so it probably wouldn't be a problem :D

Oh well, I guess they're all on a vacation in Tallin. If they don't get back soon, you may also check the sixth cliff from the left.

Yes, you can see another player if you are both in the same world. It usually happens by a pure luck (no, it's way more likely than probability divided across all worlds). But you can achieve this intentionally by sharing save files or just redeeming the same cheat code. Although keep in mind that this technology is maintained by the same person who made horses for this game, so it is highly unstable. If it breaks please contact support so we can finally fire them.

Hori stands for horizon. Forge stands for forge.

Frankly speaking I’ve been asking myself the exact same question for several months now.

Yes, updates are posted occasionally. But in most cases, nobody knows what's inside. Even I.
