The Core is a fun, medium length puzzle map which includes five puzzles which in short includes a bit of everything.
This is the second version of my previous map The Five Puzzles which had some bugs in it which has been fixed in The Core. I also didn't test the previous map in 1.9 but as it turned out it didn't function well on 1.9 so this time I'll be sure to tell you guys to use a 1.8 version.
I haven't found any problems with the map after testing it for about four times so as long as you use the supported versions (any 1.8 version) there shouldn't be any problems with the map.
There is only one hint which is on the last puzzle as the last puzzle might take some time to complete but only use the hint if you have really tried.
