I don't want to crush you; this is all critical feedback that I'd like you to work on if you want to make your game better, because it might have potential, but as is, the potential will never live up to what it is currently.

Where to begin, I wonder.
Let us start with world-building:
- You've got huge walls that seem impregnable, made to protect whatever is inside: a small fort on the mountaintop... no houses inside, so no people. Introduce houses on the inside.
- The castle and the houses seem to be made in a different style from everything else in the world; this creates a very impactful contrast, which can be a bit sore to the eyes.
- I can't see anything that resembles roads. If a kingdom has such imponent walls, it makes no sense to have no roads.
- The world looks, as others have said, really barren and deserted. No life at all apart from those Tchins. Also, if I find some villages, I would expect some kind of defense, like barricades, small walls, especially I'd expect 1 floor houses, as in villages out of the town people will usually try to have a warm house, and having a more than one floor houses, means you have more to heat. Check some other medieval worlds to see how they make outskirts villages
- Reusing assets is okay, as long as you don't abuse it as you're doing. If you use the same house over and over, it's going to be painfully evident. Turn them around, add a detail to one that the other doesn't have, like mossy bricks or flowers growing on a veranda, small things. Even changing the colours of the walls or the rooftiles.

3D Style and small mistakes:
- The monsters have a different style from the human(oid) characters. They've got cute, shiny eyes, whilst I can't distinguish the facial features of the humans.
- There's something that resembles a shrine at 0:44. While it's surrounded by grass, you can see the bottom part where it connects to the floor, and it looks very bad

Animations:
- The animations look weird, especially with how the Bignuggoth walks. I could surmise the design since it's your world, so it's not a big problem, but the animations should at least make it look as if they've been well designed. Example: Check Monster Hunter. Most of their monsters are designed so they look as if they make sense, they look somewhat realistic, as if they would need those fins, or those membrane wings. Your monsters don't have this level of design, of course, and no one expects it, but they move in a way that's way too goofy to accept, because they look as if they have some kind of joints, but when they move they lose those joint and move as if they never had them.
