The vertically projected atmosphere is trumpeted as the winning difference between Raid Over the River and other shooters, though our attention was more drawn to the fact that in one of the game's three time periods, your futuristic aircraft is switched out for a rather disagreeable dragon. Bolstered by the presence of a winged beast, it shouldn't take Nibris too long to get hold of a publisher (or the English language). In the meantime, have a look at the first colorful batch of screenshots.
