Blob Land is a simple homebrew NES platformer that was made for #1JAM Uno game jam. You play as a blob whose goal is to get to the portal on the other side. Enemies and colored blocks are in your way, but thankfully you can jump and consume potions that can allow you to pass through those colored blocks or even stand on top of them.
In this run, LoganTheTASer beats this game in record time without resorting to the level skip function.
You can play the game here.
Watch this run being played back on a real console.
