The level portal is a forum specially designed to allow people to share levels created in Super Mario Flash.
Super Mario Flash does not save custom made levels directly into the game, to allow players to save their creations, SMF generates
a simple text containing all information needed to re-construct the level, the level code.
A level code :
Use the "Submit Level" link at the bottom of the portal. Be sure to copy the level code from the game correctly and paste it in the level code field. Then, name your level, write a short description and press the submit button. You are limited to a maximum of 2 levels per 48 hours.
-You are limited to a maximum of 2 levels per 48 hours.
-The portal is in intensive rating.
-When the portal is in intensive rating that mean there is too many levels who dont meet the requirements to be moved. We do this to allow all levels to be moved or played. No one really play or rate levels located in the last page of the pending section. -The intensive rating start when there more than 100 levels in the pending section. -The intensive moving stop when there is less than 15 levels remaining in the pending section.
All new submitted levels are placed in the pending levels section of the portal. Your level will now be visible for everyone. Mario flash players will try the level and rate it. Then after a certain time, your level will be moved in another section based on the ratings your level received and the sections requirements.
