While the player is able to pause the game to inspect the level and status of the lemmings, skills can only be assigned in real-time. Lemmings are initially released at a rate predetermined by the level (from 1 to 99). The player can increase the rate as desired to a maximum of 99, and later decrease it down to, but not lower than, the initial rate. The player also has the option to "nuke" all the remaining lemmings on the screen, converting them to Bombers. This option can be used to abort a level when in a no-win situation, remove any Blockers that remain after the remaining lemmings have been rescued, or end a level quickly once the required percentage of saved lemmings has been reached.
