Perfect Lemmings style flash game
As a hardcore Lemmings fan, I've been wanting to do a Lemmings-style Flash game for years and I guess I don't need to because you beat me to it. The first 10 levels were really easy for me but then they got REALLY hard. The last one, Level 15, took me 2 hours to finally save 20 students, but when I finally figured it out, I managed to rescue 23!
This game was almost perfect. My only suggestion is that you add CODES so you can resume the next level later or go back to previously completed levels.
Great job!
