I've been trying to find this game for a while now, it's a bit fuzzy, but I hope this community can help me!
System: Windows
Year: Somewhere between 2005 and 2012 (don't know if it's still active)
Perspective: Switches between platform and 3d (top view)
Art style: smooth, yet colourful.
Environment: Differs per characterlevel, the beginning is a bit of a open wood/farm environment, then moves to the beach. (Haven't played it beyond).
Mood: It had a happy mood
Genre: It is a fantasy adventure, with basically everything being played online with the community.
Gameplay: The interaction was keyboard based (the way i remember it), but i thing you could also use your mouse. Your character gained exp by defeating monsters (the first monsters you'd encounter were wood logs and sheep). Every level was basically a mission, defeat the monsters and defeat the boss. The first bosses were some sort of wolves. There was some story behind it with a professor turning them, but i can't remember this clearly.
I hope you can help me!
