Super Mario Bros. Wonder Devs Reveal Unused Wonder Effects
The developers behind Super Mario Bros. Wonder recently shared some unused Wonder Effect designs at this year’s Game Developers Conference.

This would have made dodging enemies impossible, so the player would have had to simply charge their way through the level as blocks broke off Mario’s head with each foe he bumped into. The development team ultimately found that the effect of Mario losing his head ruined the feature’s visual appeal, hence why it was cut from Super
