2) For those who haven't quite got the hang of how to use new NeoLemmix features - I'm not sure if you've worked with SuperLemmini, which has a few new features, but NeoLemmix has even more (even if it doesn't have all of the ones SuperLemmini has xD)
Yes, this definitely needs to be in the tutorial. Some people have made NeoLemmix levels, but I'm the only one so far who actually uses the NeoLemmix features (gimmicks, objects, skills, secret levels, etc.). This is probably because the people aren't too familiar with the new features and the new mechanics (which was probably why it took me a while to solve Dodgy 18 "The United States Method")
Some suggestions:
-A list of mechanics changes from traditional mechanics.
-A chart of gimmicks; one column has the name of the gimmick, one column that explains the gimmick, and one column that has at least one small image demonstrating the gimmick.
-The same applies to chart of NeoLemmix objects and NeoLemmix skills.
-How to create adjustable VGASPEC levels.
-If you made a level with the traditional editor, but now want to adjust the size to remove the unnecessary space after NeoLemmixising it, a tutorial on how to shift the level and adjust the level size.
-If you ever implement it, how to add achievements.
-How to set up Test Mode (a couple of people have trouble with this one), and how to change the configuration to when you start the level, the Pre-postview screen, go straight to the level, etc.)
-The tutorial for the Playtime 10 Gimmick.
