Hello Colorful Arty,
I have attached my replays for this small 12 level pack of rejected levels. I'm well aware that you ended up releasing the actual pack with less levels than intended in each of the ranks, and so these replays won't really be of interest to anyone, but I'm just posting my replays for completeness, since I have plans to eventually post all my replays in the right level pack topic, including demos and very small packs like this. Hence, my feedback is not going to be too long, particularly since there's probably no plans to update these levels due to being rejected from the main pack.
I actually started playing this at the beginning of this month. I gave up on this when I couldn't solve Not good enough 3 - The Tower of Babylon. I ended up skipping it and I was able to solve the next three levels, and then I got stumped on Not good enough 7 - A lounge of lizards. That's when I gave up on the pack, and I didn't come back to it until last night. I surprisingly was able to get through both levels 3 and 7 easily this time. For the former, I simply was thinking about the solution the wrong way and in an overcomplicated manner, as I kept running into the problem of thinking I was a skill short. It is actually quite easy. For the latter, the challenge is just getting past the lizard trap, as it apparently triggers extremely fast, so fast that even at a 99 RR each one gets devoured until about the 4th lemming or so, which will be able to get past. Once you are successful in getting one past it, the rest is very easy. It probably makes a huge difference when they're climbers, as I think they're slower than walkers. I also consider level 7 the hardest one in the entire pack, though it's quite difficult due to the execution, not the puzzle aspect.
All the other levels were pretty easy, although I say level 8 was extremely annoying to set up, as I had to rewind so many times in order to finally get all the builders in the right positions in order for the miner to use all 3 sets to release the crowd from up at the exit area. Easy solution, just very annoying to execute. The following level, Not good enough 9, is very easy, just very tedious and repetitive. Not good enough 10 - Crazy Egypt was a really nice level, but is somewhat annoying to pull off, considering all the timing aspects of the level. It does rely on the solid ceiling, so perhaps that's one of the reasons why this level was rejected? It can also be difficult considering that the skills can surprisingly run out really fast, particularly the stoners and builders and cloners and, to some extent, the digging skills, but only if you take the wrong route, like I initially did through the pillars at the bottom, when I later realized you can just bomb and bash right where the water is. Finally, the pack closes off with a level with the trick of two digging skills crossing, in this case a bahser and a digger.
Besides most of the levels looking quite nice, the music choices were also pretty phenomenal. The only standard one was the music from the Highland tribe of Lemmings 2 for the penultimate level. I really liked the ominous sounding music for the shadow tileset in Not good enough 9.
In any case, I'll eventually get to playing the actual pack. Overall, nice job with this very small 12 level pack of rejected levels.
