now for a really challenging one. this game is called YGS2000 (虫姫さま), i believe. this game is similar to one of kenta cho's games, rRootage, in that it is just one ship against a boss. the focus of these games is for building your dodging skills by playing through massively difficult bullet patterns at different levels of difficulty. this game features 65 different basic patterns, each with 99 levels of difficulty. you can choose to either have bombs or lives, as in having one more bomb gives you one less life. the object of the game is to stay alive, as you cannot attack. the bombs only clear the screen of bullets. some of the bullet patterns if not all are based on other arcade game patterns, the 65th pattern being from a cave shooter called Mushihimesama. the graphics are not anything to speak of, but the massive amount of patterns to try more than make up for it. this game is a fairly small download, and could really help you build up your dodging skills. highly reccomended. download here.
