Divided into two worlds with their own set of rules, test subjects must find a way to pass the test and accomplished their shared goal. Isolated Subject, by Crneumre, is a platform puzzle game where you must figure out what is the special action in each of the worlds, and then switch between the rules to succeed. Nothing is explained to you, and you must experiment to find out what the secret action is. You only have movement keys of [W] for jump and [S] and [D] to go left or right respectively. In some worlds you can double jump by pressing [W] twice. In others, you can remove blocks by walking into them, and in still others even more clever and diverse tricks exist. Within these worlds is the exit door that must be powered by the glowing blocks. This is a case of a team effort that is spread very far apart in complete isolation. Are you clever enough to figure out the tricks?
Isolated Subject is a game about experimenting. You have to take some subjects' lives for the greater good of discovering the unique behavior of each level. Upon death, you respawn in the starting point, but what you had created or destroyed in the world stays the same. Only hitting [R] will undo what has been done. Only in a few rooms do you get a hint at what the hidden trick is. When you hit the [spacebar], you can then switch between the world's rules. For example, if you must get on a high ledge, but world three doesn't have double jump, you can hit the [spacebar], then the number two, and now you have the rules that correspond to world two and can easily double jump to your destination. But not all the behaviors are straightforward either. What's great about this puzzle platformer is that it's a balance of two riddles: what makes this world special and how can I use that to win the game? With its eerie music and feeling of loneliness Isolated Subject is not only clever and cunning, but beautiful and involving in its own way.
