Here's how the game will go:
Aliens will be whooshing about behind a closed curtain.
The curtain will be opened. The amount of opening is dependent on the current game level. i.e. Higher level, smaller gap. Focus attention at the gap and when you spotted an alien whooshing pass, try to remember its look.
Once the alien whooshed pass the gap, the curtain will close and 6 aliens will be presented. Tap on the alien that whooshed pass earlier and do this before the time ran out.
Correct identification will bring you to the next level. Incorrect identification will end the game.
Game difficulty increase at higher game level with faster whooshing speed and smaller gap. At level 40 and above, 2 aliens will be whooshing by instead of 1.
