Well, I haven't been very active on the forum lately, because I've been working on this. My first level pack left a lot to be desired.
I made quite a few mistakes when designing it. I rushed to meet a deadline that didn't exist. I didn't throw out bad ideas. I tried to do too many things at once with it. The levels were not tested well. Most importantly, I lost focus on what I was originally intending to do. The end result was a pack that had a few good levels, a lot of mediocre ones, and quite a bit of hot garbage.
This new pack I'm working on aims to avoid all those pitfalls. It will be an easy pack; I've named it as such to constantly remind myself of this. There will be three ranks, and the difficulty should never exceed late Tricky / early Taxing stuff. I'm aiming to have at least 60 levels in the finished pack, though there may be more. Currently, I have 31 levels built for this pack.
Attached is a demo with 6 levels. Pre-level text describes some of my thought processes for the level designs.
This demo should work with the latest stable release of NeoLemmix. The final version will have custom music and title screen graphics, but I've left those out of the demo.
Enjoy!
