You don't understand man. An exe is when your program is compiled to machine code. Its practically unreadable by humans, and Construct has no way to (at least not conventionally) mess with a game after its been compiled. C++ does not run in real time, it compiles. I don't know exactly what language Construct uses or how it compiles, but even languages that are interpreted in real time like Python, you don't just mess with the memory after its become a program. Unless you're a genius with binary or hex, you cannot feasibly work with a game after Construct has exported it.
