All right, I posted this idea in the general MM thread of having a friendly monthly competition of everyone making a Mario Maker level based on the same theme.
The challenge
A monthly challenge to create a Mario Maker level.
Anyone who wants to participate, makes a level based on a theme, decided on beforehand by the winner of the previous challenge.
The theme will usually be two chosen Mario Maker elements, but can be any restriction.
Only one entry per participant, and no revisions once you've uploaded your level, not until after the challenge at least.
Deadline will be roughly a week. The challenge starts the first saturday of the month, and ends on Sunday of the next week.
Don't upload your level until the next weekend, so all levels can be played at the same time.
Participants and other forum members who play (all) the levels can vote on a winner.
Oh and I thought it would be a fun way to sneak in some site promotion by mentioning NE in the description.
Theme
For the first challlenge I went with two Mario Maker elements to build a level around, this seems to be the sweetspot for Mario Maker levels to focus on, but the theme can be any restriction you can think of (within reason). But it's more productive to keep things simple.
Voting
Vote for the level you like the best. You have one vote.
You can't vote yourself.
Players can vote too!
In case of a tie ehh, I don't know. Initial idea was to have the players tied race a level not made by them, but now I think of it, it's easier to just check the actual hearts they got on their levels and compare.
Winner gets to decide next theme
