Pros and cons are down below) Check out me vid (the game is the 3d there):

Advantages:

1. The game was very cute. The artsyle is awesome and very much fitting to the concept!

2. The concept of learning magic spells is a very clever way of expanding the gameplay and making it more interesting. You give something to wait for. Great job!

Disadvantages:

1. A bit confusing about what actually happened. Maybe one more line about the story? Who's dead? Why curse? A bit more lore would be perfect. Tough, leaving the game this way makes a player things which is also a nice move.

2. The layout seems a bit empty. Maybe a bit more complexity to the background would benefit the game.

Overall:

I enjoyed it very much! Short, cute and interesting experience, thank you for developing it!

Hope my feedback was useful!
