Only 'version 3' has been previously released - I barely remember releasing it, but I know I must have because it's on spatang. I don't even remember how I released it - emailed it to people? Uploaded it on my old Freewebs page?Anyway, be amazed at the amazing progression of a level over the course of four versions!
PS In case you're wondering why the file size for version 4 is so much smaller than the other three, it's because I edited it with Mindbelt, which RLE-compresses the output level, while KeenEdit/KeenWright does not.
PPS I also have a couple of other unfinished levels from a long time ago floating around on the same USB drive, as well as a level made by my sister when she was 11. I showed it to her like a year ago, and she had no recollection of it.
I'll probably upload these at some point.
