Sorry if this is in the wrong forum!
I remember playing an old KS level called "The Meaning of Life" or something. It was really weird, it had bossfights, it was really difficult, there was a character that was a boot that made weird noises, and the sound design really stuck in my mind as being clever. My mind may have merged two levels into one on this one, not sure. It had different endings where you would arrive at different interpretations of the meaning of life. Ring a bell anyone?
I can't find it.
