"Porrasturvat - Stair Dismount" is the name. I think it was the winning game in Assembly 2002's Game Design Compo. I posted a thread about Assembly when it was going but no one replied. Anyway, more info about Assembly here: http://www.assembly.org/ and Stair Dismount's own homepage here: http://taat.fi/taat/porrasturvat/

Btw, I really don't understand how they get those scores that are in the all time Top 200 list... My personal record is some 80.000 but the best score there is more than ten times bigger (and the worst is about 5 times bigger)...
