The main problem with the protagonist is that he can't do any spell, so you have to beat all the levels exclusively by jumping. In fact, the only button you can use besides moving left and right is the jump button.
In WizardWizard there are more than 20 levels, although all of them are pretty short. The good thing is that it follows the line of Super Meat Boy and VVVVVV, which means that it's a really difficult platform game. It would be normal for your character to die at least a hundred times before you beat the game.
WizardWizard is a platform game with a really fun gameplay and a really funny story. In short, it's a charming game with excellent retro graphics.
