SimpleCard 1.4 will be out later this week, perhaps the beginning of August.
The items in the current to-do list will be completed with the exception of fullscreen support, plus a new feature which will let you copy the settings of buttons from one card to other cards along with the graphics and text.
The score system will work much in the same way as GameMaker's counter (when score = x, go to card y).
A timer which moves from one card to the next may also be implemented.
One other thing that I should mention; you could make games with or without the text area, as well as being able to change the font, colour and size of the text area. This could be useful for title screens.
There is also the pressing issue of not being able to play games without compiling. I'll have a look and see what I can do about that; most likely it will have to compile into a temporary folder and launch itself.
EDIT: Could you sticky this, Ghost?
