Spelunker is possibly the hardest game I have ever played. Deaths are cheap, the pace is slow, your weapon is useless and there is only one song that it plays. Why can't I stop playing it?
I'd enjoy Spelunker a lot more if there was a way to disable the "fall one pixel and you die" option. Jumpman had the same problem: stepping off of a tiny little hill will kill you, but jumping off of it won't??!!
