A.R.'s Puzzle Levelpack (also known as Unknown I's 1st Levelpack) is a pack of 9 custom Keen 1 levels, most of which involve mazes.

Some of the levels use the tiles in an interesting way, such as using the cyan mosaic tile from Capital City as wallpaper. There is no pogo in the whole pack, even though some levels require the pogo in order to be completed, therefore the player must use the C+T+Space cheat in order to get it. Level 15 is a major edit of the Second Ice Shrine from the original Keen 1.

This levelpack is notable for being the first to have a new world map that isn't an edit of the original Keen 1 world map. Some of the level entrances lead to nonexistent areas, where Keen would get killed as he enters them, possibly indicating that the pack is incomplete.
