Very enjoyable and relaxing. It was a very wise choice to go without any little people in the game, as I feel it'd ruin the ambience - but I do love the idea of being able to see and hear signs of them dotted over the place, like with the tree cutting sound and that of the motorbike, etc. Maybe in a future version add a little chimney to some of the houses so you can give them animated smoke plumes, like someone's in the house?
The only REAL issue I have with this game, however, is that the prices of the "packs" you can buy eventually raises to be so high it's borderline ridiculous... I understand why you've added it though, to encourage the player to use all the packs available to to promote the less rapid, more laid back approach to enjoying the game. Personally, in a next version if it were me, I'd implement something like a rainstorm that comes every now and again which lowers the cost of the packs by a third or something.
Aside from that gripe, this game (or more like a relaxing executive toy? There's no real win state) is a lot of fun, the sound design is very peaceful and it's just so charming. I think I'm gonna go play it some more!
