The difficulty is Easy. It's an enjoyable little beat-em-up style of level.
Also, I believe that the name of the level is supposed to be "Rambo It".
Ah! I took that character to be an 'l' (lowercase L), but seeing that map, I have to agree, and will rename it as you suggest. With a space between Rambo and It in the thread title, and RamboIt for the folder and files.
The type font used in the software used for file transfers on this laptop, and the servers, makes absolutely no visual difference between an uppercase I and a lowercase l (unlike what we see here in this post. So I hope that the filenames of RamboIt will be true.
I will ensure this thread refers to RamboIt, and see if the links work.
