The first game in the franchise, which is available on GOG, is excellent! It has the perfect formula for a successful Metroidvania: a pleasant soundtrack, beautiful pixel art, lots of items, enemies, areas to explore more than once, very good combat mechanics... And from the trailer for this Timespinner 2, we can see that it also has everything to be an excellent sequel!
It needs to be released here, because the franchise needs to be complete.
