I was looking at the fsf directory and decided to try out gnujump. The game is pretty hard. I told my son I got to level 9 (apparently I had made it to 15 at some point). He kept playing until he got level 18 at which point he said he never wants to play it again.
Yeah, kids today! I tried to show mine the original Lemmings, and they gave up after the first hard level. (“You have to start all over???”)
Ahh, that brings back memories
