Thank you for your review. I agree with you, its always better with sound but I didn't knew a way to do them in 5 minutes I'll chek whats you said. Finally the timing is not suppose to be that tricky at the start of the game. But I based the difficulty on my personal gameplay, so maybe I'm more used to the mouse (FPS player), than other people. With more trials I'm sure you can increase your score even further ;-)
