The tutorial in the beginning was nice to have since there are quite a few combinations of abilities you can use. I really like the earth spell and how it interacts with the environment. I also liked that each level was themed and you could tell what the surroundings was supposed to be (the platforms could also be textured instead of a solid block). The combat was nice since you had three different attacks.
I think the game has a lot of potential with the spells and how they can have special interactions. I think it would be good to have doorways be more clear and also a clearer indication that you are picking up a spell. Attacks could also have more effects and not just disappear.
