Lovely game. I must agree that it is different than the Shelter 1. I like both of them. Shelter 1 is great for begginers and also for people, who want to have emotional story without a word! This one contains words and is more like a sandbox, but still interesting. Few things are a bit annoying for a player of the first game, but you get used to it. There are still some things left for the player to explain, how he/she likes. And hey, lynxes are very cute (well after Shelter 1, I must say that badger is cute too, but I did not think about it before). Don't worry, you can expect nice bugs (like falling through the terrain in some bushes or on the stones, or rabbits running from you in sitting position - but hey, they are then quick).
If you buy it, I recommend to notice the "Saving" caption in the right bottom corner. Because if you mess something from last Saving moment, you can hit Esc and select Load and get back to last save point. But not further. And another thing, you don't need to finish with any cub, but it is preferable to end with at least one.
