Hello, I've been working as a flash-developer for 6 years. I like to develop educational applications. I have experience of doing it. I can create the game you need fast with the best quality of work. The game content can be loaded externally, so you will be able to manipulate it: create a new levels, edit it without programming. To achieve this the XML file can be used. Of course, if don't need this feature, I can embed all this pictures and sounds into the flash.
Best regards, Volodymyr.
