Tux is just getting ready to go fishing when all of a sudden, he receives a message. The message states that his home, Icy Island, has been taken over by the Snow King, and a new Fish Tax will be imposed. Tux is furious! How dare the Snow King take away his fish?! Help Tux overthrow the Snow King and stop him from taking Tux's fish away!
Play through 41 action-packed levels with some puzzle elements, taking place on the snow-covered Icy Island.
Health is represented by hearts which are restored by collecting coins, making a wide variety of difficulties possible without making the game frustrating.
Powers are obtained by using special items directly rather than by transforming. Some such items include fire flowers (which shoot fireballs), ice flowers (which shoot ice bullets), and lanterns (which light up dark areas).
Your character's state is reset upon entering a new level, allowing more fine-tuned level design.
Items are picked up automatically and either used or thrown by pressing the "action" key.
Running is automatic. To walk, you can either hold the dedicated "sneak" key, or you can use an analog stick to finely control your speed.
You will never be forced to backtrack further because you failed too many times. Lives are infinite and checkpoints never stop working.
The game is fully accessible to colorblind and color deficient people.
Feeling creative? You can create your own levels for ReTux using the Tiled map editor, and share them with your friends using the Import/Export options.
