Short info:
Well.. it's a Tetris clone. Do I have to say more? Maybe I do as there are many variations of Tetris around.
This version tries to follow the Tetris
specification
by Colin Fahey. According to Colin his specification follows closely to the pre-commercial
MS-DOS version's behaviour. (Vladimir Gerasimov's PC version is the first port of
the original Electronica 60 version by Alexey Pazhitnov) As the
MS-DOS version
is available freely from the net, you should be able to compare yourself.
(I haven't yet and even if there's some differences, I still might stick to
my implementation for some weird reason. :-)
Since I know you aren't interested of reading the specification, I tell shortly
here what is missing that you might expect based on your previous experiences.
