 AllGame 's reviewer was satisfied with the game 's graphics but criticized how its bosses were designed , elaborating that " the Sinistars ... simply don 't instill the same sense of sheer panic [ as in the previous game ] . " Vincent Lopez from IGN noted the game 's similarity to its predecessor and complimented its graphics and the addition of a wide variety of weapons as well as other technical features . However , he viewed the weapons as " more of a checklist than an actual asset . " He stated that Sinistar : Unleashed " feels immediately familiar to fans of the original , while adding just enough new features ( and a completely new graphic overhaul ) to make this feel now @-@ dated .
