Circle Test Suite

Circle Test Suite is a physics-based puzzle game set within a series of test chambers. The player directs a character who carries out commands on their behalf, with the goal in each chamber of bringing an object to the main target and activating it. The character is equipped with a tool for interacting with the environment, and each use of that tool costs one action point.

Action points are earned by discovering new test chambers or by activating optional targets found along the way. When the main target is reached, the number of points spent must not exceed the number earned, otherwise access to the next chamber is refused. Any points left unspent carry over to later levels. The character can also adjust the speed at which time passes in the game’s emulator, and players may save a snapshot of the current state and return to it at any time during a test, although saving a snapshot costs one action point.

The action points remaining after the final test make up the player’s final score. This can be improved by revisiting any individual chamber to better a previous result, or by restarting the whole set of trials from the beginning. Attempts are unlimited, and players can move between any trials that have been unlocked at any point.
