This isn't a game, it's a screensaver.
From the reviews on the store page, I thought that it would have some kind of events that happen to liven things up. You could grab random objects, arrange them, see the seasons change, maybe there would be some birds flying around. It gave the impression that even though there wasn't a point to the game, the experience alone would be fun, and you'd stick to it just to see what would happen.
But I never saw that. I played for 20 minutes. I spun the camera, i played the keytar, I zoomed in and out, I found every feature on my mountain. It rained, i spun the mountain to make the clouds go away. I saw the little thoughts my mountain had. But nothing happened. I pressed every button, manipulated every control I could think of, and made as many patterns with my mouse as I could imagine, and nothing happened.
I can't honestly recommend it, because I've had more enjoyment from that Windows '95 screensaver about a maze (with the rat in it) than I did from this game. Maybe there's more to it than I thought, maybe you need to leave it on overnight for something to happen. But it's not presented in a way that makes me want to stick around to find out.
