Simple, But Effective

Reviewed By: GamingWithDrew on 19 Dec 2022

I really enjoyed this one. I liked the simplicity of being able to choose between vanilla SMB1 or Wario Bros. by simply hitting down on the d-pad and I liked the alterations to the palette, music and dialogue. Not super fancy, but it doesn’t always need to be. Enjoyed this one quite a bit.
