If anyone wants to try the level editor, here's a quick level I made so you can get familiar with it:
-__d___RRRR______RGGG___g__RGSG_P1g2_BGGG_uBgB_RRRRBBB_______
Hover your mouse over the panel located at the bottom of the editor to see the "L" and "P" buttons.
Hit the "L" button in the level editor and paste this code in to load it, hit the "P" button to play.
If you make anything, get the code by hitting the "S" button and share it here :)
