This is a not-entirely-faithful port of the original game. The mechanics are somewhat the same as the original, although I have no extensive experience of that version and so this is more an exercise in replicating something and then extending it.
To that end, once the core gameplay is completed, additional mechanics will be added to the game in order to see how that changes things. Maybe we'll end up with something better, or maybe we will not.
