I loved it! Anyway I'm going to give you some feedback because I think it's important:
In the caves it was weird seeing Gramps sink in a rock and then just appear when I got to the gate, like the deity just let him free? I don't know, maybe it's a me thing, but it felt weird.
I didn't get the carrots, stars and moon thing. I got close but I ended up looking the walkthrough guide.
Also there is this place where you can get stuck falling forever.
Anyway, it was fun chilling, digging fossils and discovering a horrible deity in the dephts of the earth. As I said, I loved it and I'm looking forward to play whatever you make next!
