Very fun game and addictive. Not only measures your reaction but also improves it, I guess. When I first started to play the game, I had a high score of 178. Then, 202. A week after, more. Now, 299. Probably I gonna have this week 300+. Oh wow, it would be even more fun if this game would include a leaderboard.
If you in a room that has a window or Windows you cannot see the dots light up and I cannot because I'm in A room with a window and I got zero points in the first round.
