Overview:
Capsized is a fast paced 2D platformer focused on intense action and exploration. As a intrepid space traveler, your ship has crash landed on a mysterious alien planet. You must navigate through the perilous environment and fight off blood-thirsty creatures to save your crewmates and escape with your lives!

Use your jetpack to fly through the alien jungle, and tools such as the Gravity Hook to manipulate your environment to skilfully dodge and defeat attacking enemies. You will be challenged - with platforming, puzzle solving, and deadly skirmishing, often all at the same time!

Artist Jesse McGibney and programmer Lee Vermeulen create an immersive alien world teeming with bizarre life-forms and strange landscapes presented in a unique hand-drawn art style. Combining control elements of first person shooters and innovative physics based combat, Capsized emphasizes action without giving up the smart problem solving of classic platform games.
