Yeah what I am finding is these things are really 100 lines or less:

I say make it 100 lines with no colons and get something as enjoyable to read as to play!
That would be way more educational and inspiring for all levels of hobbiests.
in fact the colon creates illegible code as peter quoted is obfuscated code
like this example you proposed of 100 lines
but maybe other people would put rules each line should not contain more than 100 characters
however in any case as you have mentioned it would not be worth it
as you pointed out in the post everything can be adapted with a sub (subrutine)
