You have been sent to a deserted world to figure out what caused it’s collapse. Press x to interact with objects and move with the arrow keys. (Annoyingly, you have to use the mouse to click on message box options, I couldn’t figure out how to fix that.) Download and play here if you’re on windows. (Game maker 8.1 can only make export as .exe.)
(To save you the trouble, getting 100% on the test does nothing, so don’t bother. Also, there is no ending, so if you think you’ve explored everything, you’re probably done. Ideally, this game would have more places to explore, less rushed backgrounds, and an introduction to establish the universe a bit.)
