I never played the original Lemming Syndrome, but I love the calculator version.
I keep coming back to try for a better high score. It's probably the most addictive game on my calc.
When about 7 or 8 lemmings get on the screen at the same time, this game gets extremely challenging and intense. When I get them all to the other side without losing any, it makes me feel good. The shark and occasional bombs spice up the game after you play for a while.
They are very good, but the background is always exactly the same.
The keys make sense and allow you to move the life raft very quickly, which you will need to do to avoid dropping any lemmings.
Overall: 10/10 of course
This game is truly a keeper that will provide you with a fun challenge again and again. Download it now and see for yourself.
