I loved Lemmings, and I enjoyed this too, although it could have been a bit more challenging, I only had to think on the last few levels. Loved the music too.
Normally I like game like this, but without knowing whats coming, I ended up without armour when I needed it, with no option but to restart the whole game. The controls were unresponsive at times, especially for such a simple game, and for some reason I kept accidently pressing spacebar and restarting the level (make restart R perhaps?) 3/5
There are NOT multiple solutions to any of the puzzles, its just not logically possible for there to be multiple solutions if you can complete it without ever guessing. If you think you have a different solution, press the 'show incomplete' button on the bottom bar to see where your mistake is (and then stop guessing and play the game properly)
