Level 21
Based on the 32nd original level.

Level 23
Appears to be an original level design.

Getting to the central zone can be tricky, and has to do with the special feature of this version of Lode Runner: you can fall on the head of an enemy for extra point... and to reach the central zone (impossible on conventional Lode Runner). This confirms this level design is original to this version.

Level 24
Appears to be an original level design.
