Well if you are that person then you are in luck! Introducing The Lost Levels 2. A fan-made sequel to the Japanese-only sequel to Super Mario Bros. This project attempts to make harder and more challenging levels than The Lost Levels did.
This project so far only has a demo available.
If any of you have any feedback about this demo, please let me know. I'm always looking foward for improving.
Credits will be available inside of a notepad in the folder of the demo.
A new demo will come out soon.
