IMPORTANT NOTE: EDEN.WAD was tested to run properly with Doom v1.1 and v1.2,
PrBoom with -complevel 0, and PrBoom-Plus with -complevel 0.

There is a severe bug that prevents part of the floor (sector 51) from being
raised when played with Doom versions above v1.2, or any source port that
doesn't emulate Doom v1.2 behavior.
