Backgrounds and sprites're from official SQ games and unofficial fanremakes. Main theme of game is Space Quest 4 (there's 'SQ12 timeline' in this game).
In SQ12 by Slash your hero is sequel police, enemy from official game. And you must find and destroy Roger Wilco
There're fun moments, nostalgia and it's nice game for fans.
In demo you must do part of Vohaul's mission. And also there're some easter eggs.
Btw, Slash Vohaul
(Dr.Slash) created several new graphics from old ones (for example, SP in timepod, SP death, SP with ancient bird, etc).
You can take English tra-file from 1st post, it's my work. I'm not very good English speaker, so it's not perfect, but you can understand main thoughts and some parts of humour.
So enjoy! IMHO it's brilliance SQ 'VGA' work.
