Only one player can use the keyboard.
If you share my opinion that most recent games in the genre have been too easy on the puzzles - then this game is for you. Also, many planets have inadequate atmosphere and some even host intelligent life that could become hostile to newcomers. Features
single player adventure
local co-op with additional puzzles designed for two players
original soundtrack
support for various controllers
support for older graphics cards and computers
over 100 unique puzzles including switches, sensors, doors, elevators, movable blocks, lasers, mirrors, driving vehicles, flying a spaceship, manipulating gravity and your enemies
Players who want extra challenge can try to collect all the hats, which requires solving some optional difficult puzzles or solving the existing puzzles in different ways.
