Ah my dear Bragatyr ! I am indeed interested in speedruns but I think that time is ...running too ! And very "speedy" !

So it's hard to watch many SR videos alas...
Glitching is some part of many speedruns but it depends as there are many different types of speedruns (I've read an article about it sooner).
Some prefer use glitches, other not etc...
About the fishmen, ah that was a fisman that killed my der Alisa for the first time on my first game with my two brothers ! I can remember it clearly ! Grrr !! lol That was during the early night, when my parents were out and we played while they were absent.. (not glorious that is sure ! ^^).
