The original poster (dr_st) mentioned something about the physics being different between the DOS and Windows versions. Can anybody (including the OP, of course) elaborate? I have never heard of such a thing before.
I played a lot of EWJ1 on the Sega Genesis. I eventually got stuck in one of those bungee jump versus battle levels. I don’t know how far I had gone, but I remember the Junkyard, Hell, an Underwater base (that had a glass submarine thing), racing a space chicken, and the gooey bungee jumping fights. Reading the above sentence really says a lot about Shiny Entertainment and how interesting their choices for themes and levels are.
I have never actually played any versions of EWJ2, but really loved MDK back in the day. The sense of humor in that game was very appealing to teenage me.
