After you guess the first time, click space to be asked again. You have 16 choices. A1-D4. Every time you fail to find them, they'll taunt you by appearing, then disappearing when you click Space. If you find them, the Amount of Times Found number will go up. The Time is how long you have been at this for. Once ready, click the Red Spinning Piece.
I realized while making this, this is NOT an easy game. The highest I got while making this was two. Then again, I was also just trying to figure out if it was working correctly, so I 100% cheated. Big shout out to @Pebble2012! He helped me out a ton on how to move the enemy and player around.
