Very well done! I love the controls and it felt like a very good variation of the game as it would have been available on the system in those days.
It does what it intends to but a bit more fluff around the main game , such as a title screen or so would have been cool. The unpacking to get the game was a bit harder than it needed to be and may put someone off but that's just a side note.
The feel of the game was great fun, nice!
