I really loved this game. (Here's the VOD of the stream):
The artstyle choice is very commendable, I think it matches perfectly the vibe the game offers to the player, and it's pretty polished at that. It really looks like a short complete game, you also nailed the game length in my opinion.
The battle system is relatively simple (and standard), but still came as a surprise how fun the game was. I think that to complement a simple BS like this the open-world exploration was the perfect choice.
I liked the choice of not having a level-up system, and instead to leave the progression bound to the exploration. In this way grinding enemies is no longer necessary for long-term reasons (Exp), but instead just to get the extra materials and healing items. That's what it makes it fit so well with the open world setting, and a very balanced one at that: I always felt my exploration got rewarded. After the second half of the game though the money became a little too excessive, I would've found other ways to use it.
And as an extra, I really liked the idea of crafting your own save points, it gave a lot the vibe of a survival game, and it's a pretty good use of the risk/reward mechanic.
The story was relatively simple, but still enjoyable. The focus was not the story though, so it's perfectly fine as it is. I liked the short intermissions of the evil dino king.
At the end the only thing is that the theme "beyond expectations" is a little weak. It's clear how both the Ufonaut and the tribes managed to go beyond some sort of expectation, but for the jam I expected more than a default battle system - even if a very interesting at that. But you could say that the depth of a default BS like this... can go beyond expectations. XD
Also, the paralysis from the hunters skill is too broken since it makes bossfights very trivial.
After the stream, I returned to the game because I was really curious of what I missed (A very good thing: the game got me really engaged). I tried the other choice at the end, and explored the mind control island that I missed.
Also, look at this cool softlock I created! C:
