@Kaywhyn Sometimes it's hard for me to make a level that is both fun and challenging. I often worry that I won't be able to repeat making such levels when I get round to making a level pack as well as future contests. I actually took a little longer on doing "Cactus Valley" than usual (Mainly because Ichotolot sorts everyone's levels by creators in Alphabetical order thus Armani's level was the first level). Breaking a level is often easier than finding the intended solution.
Another thing I want to point out is that for my 3 entries that I only used Classic Lemmings styles. While I find using classic style easy for me. I'd like to use L2/L3 and user created styles for future contests. Orig_Marble seems to be a popular style to use since I used it as one of the styles for my R3. Kaywhyn used it for his R1 and Ichotolot used it for his R2. I also made my PFP using the Marble Tileset.
This particular contest was pretty small (Only 12 entries from 4 people) so I definitely believe that the next one will be much bigger considering that the Slider and Laserer will be available in the next contest.
