Observe.

===================== The Story =====================

Your character is named Mason. After a tragic event, you wake up in the middle of the night unable to leave your room. Your computer screen lights up;

"Catch all of the anomalies and we will let you out"

Left with no other choice Mason boots up the first level.

===================== Character Controls =====================

W,A,S,D - Move

E - Basic Interactions

ESC - Opens your clipboard

===================== The Gameplay Loop =====================

Once a level is loaded up, there will be no anomalies present. Get used to the surrounding environment and once you're comfortable, use your clipboard to mark "No Anomalies" and click "Done, then Confirm". You will be sent back to the start of the level with the chance of an anomaly appearing. Be very careful, somethings might not actually be anomalies. If something disappears over time it is a false anomaly. 

Anomalies can appear in groups larger than 1, keep an eye out.

===================== Playtime =====================

The playtime depends on the player, submitting a wrong answer resets your progress for the run. Once you complete the level your game will save that data. Which will then unlock the next area and prompt the past level as "Completed"
