Once you figure out how to collect coins and gems, kill enemies, and dodge their spells, you’re good to go!
Then you get to spend your coins and gems on collecting characters (that all have different spell powers), and leveling up your power-ups!
Playing with different characters changes the spells and strategy you might use, but it’s still just hold down to run and move your finger in whatever direction you want to go.
Overall, it’s fun and challenging, but not too challenging (at least so far)!
