I didn't have high hopes because I'd had many other apps made cheaply in the past.
However, this app was surprisingly entertaining. Because it does not require internet access, I could play it even without wifi or in airplane mode. In addition, there are no advertisements within the game.
It's also cool to see all the different spells you can cast. It's also amusing to see what happens when you purposefully make a mistake.
However, after the first 30-50 levels, it becomes repetitive. They begin reusing the same spells. But, to be honest, I don't mind.
I wish they had a spell book with all of your previous spells in it. Apart from that, I enjoyed the game.
