asciiportal is an excellent little game. Here are some maps I've made for it.
Current version is version 2.2, comprising 2 maps, designed for asciiportal 1.2c. Unpack the file into your asciiportal directory, then run asciiportal -m mechanist.
These are intended to be rather difficult, and evil, but also fair.
Current version is version 2.0, comprising 10 maps, designed for asciiportal 1.2c Unpack the file into your asciiportal directory, then run asciiportal -m evil.
This is not due to me, but rather to user "ivanq" on the now sadly defunct asciiportal forums.
I'm putting it here because I want it preserved and indexed.
This map implements Rule 110 in asciiportal, hence showing that asciiportal is Turing complete.
