Ikasuze! Koi no Doki Doki Penguin Land MD is a puzzle-platformer game released exclusively on the Sega Meganet Game Toshokan service. It is the third game in the Penguin Land series, following Doki Doki Penguin Land for the SG-1000 and Penguin Land for the Master System.
The goal of the game is to help the egg reach the female penguin at the bottom of the stage. The egg can drop a maximum of three vertical spaces before cracking, and can also be destroyed by a number of hazards or enemies that touch it, and its destruction at any point means the player has to start over at the top with a fresh egg.
Due to being a scaled-down downloadable, Ikasuze! Koi no Doki Doki Penguin Land MD lacks the level editor tool of the previous game. The player will be returned to the title screen if they lose all their lives, but can start at any stage they've already completed.
