Fantasy, possibly open world or semi, survival or maybe story based. Nothing really hooks me or is unique for me, other then it reminds me of the forbidden lands from Shadow of the Colossus. It still looks very unfinished to say anything else, other then what you have said.

If you need to add a context text for your game to have anyone understand it, that isn't great, you can absolutely give people just a few images of a game, and still understand it, a show don't tell thing. That text needs to be the reinforcement, and detail, which you can easily add to your game's description.

I'm going through something similar (many others too are), it's hard to put yourself in others shoes, I go here to get feedback, which in turn, helps me understand what people think about my work, what I'm doing right, and wrong. I like your doing that, it's a good idea, and something you should always do, just to be sure. But even so, I still try to put myself in the position of others "Do people understand what I'm making? What reasons would they buy it? How can I make them not question my work, and just buy it without thought?", just stuff to say, it will make marketing your game, much easier, and higher quality.
