Is it really working properly?
I can´t get past the third patient. One option gets you to the congratulation page of the previous patient and the other one leads you to game over.
Anyway, its a good idea, but it needs lots of improvement. Find some sound files to spice up the action. Then, find an artist to make you some images. And if you can´t find an artist, make a better photo selection, because it´s very strage to treat a female patient and see a pic of a female doctor teating a male patient.
These are the improvements you could make without using AS. But I think that if you have made the game like this, it´s because you don´t know about variables and that sort of things... If you want to dwell in such matters, search for help on how to randomize situations.
I hope to see an improved version of this, keep working on it.
