I decided to make this because I had free time + I wanted to.
This is basically a mashup bringing the musical references in the song
to a visual perspective. Not only I put the name of the song but also gameplay of where it comes from in the most creative way I could possible.
I don't have adobe or whatever so this is basically the best I could do.

The gameplay of Captain Toad was taken from packattack04082's video of their walkthrough of Captain Toad Treasure Tracker
The song used in the video is Brian Tyler's "Level Complete" from the Super Mario Bros. Movie Soundtrack.
The rest of the gameplay was directly captured from my Nintendo Switch.
The reason the video is 4:3 because its easier to edit games like SMW or SMB3, etc.
