Description:
A large collection of levels made for the Community Contest 12 that was happen on 15'th of January, 2016. Originally published by Eclipsed, and then was been re-published by TLtimelord to include missing levels. However, original download is lost since Eclipsed's original post got been erased due to his quit from the community for personal reasons.

It's a chance this set is made for the LunaLua v0.7.3.0, and possibly compatible to SMBX2 Beta 2.
