The Lost Penguin is a very charming puzzle game.
The aim is for you and all your friends to reach the red flags.

There are 70 levels of varying difficulty spread over three worlds (1-star, 2-star, and 3-star levels).
You can only move as long as you have energy, and moving costs energy. So you have to plan ahead to always refill your energy in time.
A couple of unique mechanics make the puzzles more interesting - my favorites are the love letters and the eggs.

The game looks really nice and cute. But while the first levels are quite easy, some of the 3-star levels are really tricky and rewarding.
