I messed around in it and absolutely love the monument. Like Kerblah's Twisted Logic maps, it's got you looking for records, BUT it lights them up when you place them. Perfect! I like the idea of records as goals and this remedies the problem of having no visual cues to whether you have completed them.
This is really the way CTM maps should go I think, using materials that make it impossible to cheat (ie: dye/collect wool). Honestly, it's always sort of bugged me that wool is the default material: lots of blocks/items could be used that are impossible to improperly attain.
Kinda wish it wasn't so large/difficult though, because I don't have the fortitude to jump into another giant map right now haha.
