I may not be an active forum poster but I have been a huge find of Giant Bomb for years. Endurance Run please?
Anyway watching the Mario Maker videos and podcasts where Jeff has discussed the lack of filters and ability to find the Mario Maker level you want got me thinking I should do something about it. So me and a friend created this.
There is a wide range of filters to find the exact level you want. An example of the type things you can find is a list of all submitted Musical Levels.
You can currently submit levels by either using the Miiverse post URL or manually entering all the data yourself. I highly recommend using the Miiverse post URL as it will do the majority of the work for you. Plus it will add your level to your very own Creator Page.
Creator Pages are an early feature designed to quickly and easily display all your created levels. Any level you upload to the website using the Miiverse post URL will automatically be added to your creator page.
We also plan on adding a "Worlds" section similar to playlists in the neat future. Create a series of levels that all follow a theme? Rebuild all the World 1 levels from Super Mario Bros? Just want to share a mix of awesome levels from other users? Add them to a World and share them with the world!
I wish I would have made this website earlier but I literally decided to do it the day Mario Maker came out. Although it's not the ideal solution @jeff probably wanted. I thought I would share it here since I got the idea from him.
