Zanzarah is similar in that you use creatures of various magic/damage types in order to fight other creatures to make them weak enough that you can use balls of different levels to collect them and use them to fight more creatures and level up (there is an ultimate goal in the game as to
why you're doing all this, but I forgot what it is, probably something about saving the fairy world).
The graphics show a fairly detailed 3D environment, the camera can be set to first or third person, and the fights are move involved as you use the chosen creature run and fly around the arena, trying to hit the other creature with your abilities and trying to not get hit.
Sadly no on GOG yet. The game title in this post links to the Steam page.
