With the upcoming release of 'Major Havoc - The Promised End' at California Extreme in 2019, there are going to be some additional mazes in the game. Technically there are slots for 8 more mazes (levels 17-24) in the updated version. One of these mazes will be the Level 18 maze from 'Return to Vaxx'. The other 7 are being saved for the best designed mazes that are submitted on this site
Folks like yourself can upload mazes to the gallery of this site up through May 2019. At that point, Jess and Owen will select the best mazes for the final release of the game. If your maze is selected, you will also get your name in the credits of the attract mode.
