The cheerful music and art hide the malicious difficulty, much like a certain bush hides most of the spikes near the end of level five! I tried my best to help Beany collect his Mystic Coins but I fear all of those failures along the way have powered up Death Wizard to a fearsome degree.
Is it my imagination or do the levels get harder after you've cleared them?
Anyway! There's a great balance of difficulty and the addictive need to try one more time, hopefully learning how to get a bit further each time.
Oh, and I really liked how the music changed up! It helped to heighten the mood later on.
