So, I've played a good chunk of it:

I like the mystery behind what is going on and the short video sequences. Also the dialogue and the scrolling text stories were well done. I was genuinely interested in what was going to happen next and what the story is about. And what all of it means.
However, the gameplay is a bit too repetitive. It's just rock pushing puzzles one after another, with no break from it. No other puzzle types too. The only time that changed was for that earthquake sequence, where you were pushing snowballs on ice and that was different because they went all the way until something stopped them instead of just 1 tile. But after that short sequence, it went back to normal. I wanted to finish it, but after the short snow sequence I saw those 5 doors, went into one and saw the old familiar setup and just couldn't make myself push through this at the time, especially through 5 more levels with however many maps each one has.
That's not to say that others might not enjoy it more, it comes down to how much the player likes rock pushing puzzles. I really don't like them much, but atleast it's still better than lever puzzles. Still, I'd suggest that it a lot more variability in tasks would be better. Different puzzle types aside from pushing rocks. Maybe also some more spins on the rock pushing puzzles. Maybe some "walking simulator" sequences between the different puzzles.
Anyway, good job :)
