Thanks again namida for all the feedback.  You've given me a lot to work with.  
If you have time, could you message me the backroutes you found in Taxing 24 and Mayhem 5?

This is the first set of custom levels I've posted online.  Naturally there a few meh ones... When I first started making levels, I just made maps that looked nice (like Tricky 5) but ultimately I would prefer to have tighter levels with creative solutions.

I'll probably take a short break before doing v0.02, and then re-work or replace the more tedious levels (you've confirmed my suspicious about Tricky 15 and Mayhem 28, for example.)

I can see why timed bombing levels are frowned upon.  I don't mind them as long as they are the "theme" of a short level.  Although these must get old after a while.

EDIT by namida: Unofficial conversion to NeoLemmix V12.XX.XX is now available.

v1.1
