I couldn't quite work out the rock cutting at first, as it felt like I should be lining it up with the 'teeth' in the idol. After that it was a lot of fun, and moreish. The overall aesthetic was great (especially the trees), the music nice as well, and I like having three separate mini-games to make up the whole. I'm probably going to play it a bit more to get a better score after rating some other games, haha.
I think I came across a minor bug though. When I tried to hit 'back' while the idol was still red after dropping a slab in the tower-building portion, the idol stayed red and I couldn't do anything after that. Outside of that, it played very smoothly, including transitioning between the different mini-games.
