I was a bit disappointed too, but wouldn't be quite as negative: It is clearly a student project, intended to run very simple code and show how the registers and memory are affected. They did read the Intel manual, and most of the instructions seem to be implemented correctly including flag behaviour; for example the SBB AL,0x69 + DAS trick works. Generating and running actual machine code might well be "out of scope" for something like this.
