Rules are pretty simple.
-You make a level
-You go to upload it (you have to be able to complete the level yourself to prove its not impossible)
-Once its uploaded you paste the level code here and if anyone wants to they can play it, heart it and give feedback in this topic.
Once more, each people who posts a level code will have said code added to the OP to make it easier for others to find. They will be grouped together under the member who made them and concealed in a spoiler. The topic will be updated with codes and level names everyday.
If there are any levels in this list that you posted that have since been deleted, let us know.
Happy level designing!
