Good Job.
This is an impressive game - It's a great "conversion" of the arcade classic, and the Flash imitates 3D-styled gameplay perfectly! If anything, it would have been nice if there was a vertical meter on the side showing the player the position of Frogger. This would have avoided some confusion that even avid players are experiencing. In addition, the Presentation, such as the menus, could use more style.
Overall, this is a great Flash game. It won't hook every Frogger fan, but it is definitely worth a giving a try.
