Great to hear your ideas. How is work on them progressing. Personally i'm working on a lemmings clone. I'm not sure yet whether i'll keep it the same as the original, or if i'll try adding my own skills and gameplay twists. The basics are in place now: lemmings walk forward, up and down steps and turn if they hit a wall. I've got the destructable scenary functioning and i'm currently working on the level editor, adding useful features.
