Lemmings Plus DOS demo - Level 8 - Bullet LemmingLemmings: 80
Save: 79 (98%)
RR: 1
Time: 4 minutes
Skills: 1 of each except 0 blockers, 11 builders
If you look at the level, you already see 10 places you need a builder. Use of the digger, miner and basher are obvious as well. With that setup in mind, you'll know where to use the bomber, and thereby losing one lemming, you know you'll have to use the last builder at the end to save the digger. That way the skill placement of every single skill can be easily deducted and the level comes down to deciding who does what.
Good: Due to the time limit, you cannot just have a single worker lemming, so you have to separate another one from the group to get the work done in time. After that you'll have to decide which of the two builds the staircase to the exit.
Bad: Separation of the lemming is a bit of a timing issue, but that's the least one. At lot worse is when to launch the bomber, due to the time limit there's only a small span of time to do so. The terrain near the wall is setup to make the builder placement unnecessarily difficult, most obvious example being the gap left to the wall which serves no purpose at all except for wasting a builder which has to be placed perfectly.
