One of the keys will glow green at the start. Follow this key. At the end, each key will glow in order from left to right. When your key glows, tap or click the screen. The screen will flash the colour you chose and it will tell you wether you chose the right key or not.
Plans for future updates: Better Randomisation: Each key has one colour and if you memorise them, you don't have to watch them shuffle. More Shuffle Types: As of right now, there are 9 unique shuffle methods, I plan to add more for higher randomisation. Wave Part?: Might add the wave gameplay from the original level. Better visuals: It can be hard to tell what the keys are actually doing sometimes, and the background is a bit bland. More Similarities To The Actual Level: This one is pretty self explanatory. Thanks to Mindcap for the inspiration for the Limbo keys from his geometry dash level, LIMBO.
