Looks awesome! Before I started playing, I noticed some flaws with the included text file (they're all nit picks).
I know what you mean by "-cl 11", but someone new to the Doom modding scene wouldn't. I would recommend changing it to "-complevel 11", or just "CL11" to make it clear that "-cl" is not a valid command line parameter.
Should be "Exomoon".
For consistency, you should change "zdoom" to "ZDoom", and "prboom" to "PrBoom". It should also be noted that the final version of PrBoom was 2.5.0. I believe that you were referring to PrBoom+ (which does have a version 2.5.1.3).
"emergencial" should just be "emergency".
Two issues here. The first one I mentioned before, PrBoom should be PrBoom+. The second is a formatting inconsistency. You use a space to separate ZDoom from its version number, but then use a hyphen to separate PrBoom from its version number. I recommend replacing the hyphen with a space, but, no matter how you do it, the most important part is that you stay consistent.
Pick one.
