Rock Pocket Games’ “Shiftlings”, a platform puzzler, which can be played both alone or with a friend, revolves around two Alien Twins who are attached to each other through a cable.
In single player mode the player can switch the controls between the two aliens on top of switching the size of the two, while in co-op mode, each player controls one of the two twins. Switching size between the two characters is an important part of getting through the tricky puzzles. The smaller size enables higher jumps while the bigger Twin can’t jump but instead is able to push boxes and can be used as a trampoline by the smaller counterpart. The Cable, that connects to two Twins, provides both challenges but also solutions to get the two through the puzzles and to the end goal of each level.
