Very unusual tamagotchi / pet game
I think the guys from Morning Fail knew, that there are sooooooo many pet games, that they wanted to try something new. And in my opinion they did it just perfectly.
There are more ways how to take care of the pet. And (as the developers say), they are planning to add more of them. You may grow your own plants, complete quests, cook, and so on.
You should be able also to grow your own animals (a pet growing its own pets - that's funny), but it should be available from second level, and I'm still in first - played for cca 30 hours.
My recommendation would be simple - just Try IT! You won't regret it.
