hello! to get to the eve area you need to jump back and forth between the holes in the scribble world (the one with the big monster you walk inside the mouth of). its set to a randomized variable so it may take some time to get it to work (its programmed like how uboa in yume nikki works) though keep in mind some computers experienced a crash in random areas of the dream (due to FPS issues) so make sure you save your game before doing it!
and for the sprites, i think you should be able to just open the game files O: if they arent showing up im not entirely sure how people are data mining the game, but you could google how to get into the files of an rpgmaker vx ace game! i did it once before with the lisa rpg games but ive totally forgotten how i did it sjfgdsfj i think theres a program you can download that should rip the files haha
