Firstly, congratulations on the site.
It works well. The navigation is neat.
From the games I played, I enjoyed:
1. Wacky Match
2. Follow Me
Suggestion:
I did lose at level 12 because of no sound/light response for quick clicking.
Each light probably has X frames and at the first frame there a "stop();" action. And you are probably using:
on(press){
play();
//check if it is correct and push to next position
}
Try to use this instead:
on(press){
gotoAndPlay(2);
//check if it is correct and push to next position
}
3. Park It
Suggestions: Highlight the car when the mouse is over it and while it is selected. It will do wonders.
Also, there something wrong with the maths of the darts game. I suggest an aimer based on two bars. One horizontal and one vertical. Both of them have a marker that performs cosine (or sine) movements. Like a pendulum.
I hope that helps. If I find more time, I shall post other suggestions.
Cheers.
