Yes I read at gamezebo they compared it to RPG game however you do not get to play different roles. Your pet does grow in abilities and skills though which is a parallel.
This game seems to take from many genres. I immediatley thought of Spore when having to charm animals and the Willasaurus even seemed some reference - though yes I know Wandering Willows is the name so maybe reading too much into it there.
This game is a lot of fun when you get into it. Probably not for the impatient or those that dislike easy games. I find it enjoyable and relaxing.
edit: I finished the game and chose to keep playing but did not get additional tasks.
When I checked the walkthrough at Gamezebo I had already done the tasks on their list of additional so I guess you can finish without completing everything and then choose to do so.
Well I will just start again
What a charming game this is.
