Forever the perfectionist, it's not surprising to hear you say that you know of ways it can be even better - and you are always welcome to update it if you do ever decide or are able to do so...but I can say that as a visual guide, as it is, it has already been helpful. I can personally attest to this.
Last Hallowe'en I made a point of making time to play Clock Tower. Of course I always have too many current games to play and too many older games to take on as well, but I'd heard of Clock Tower for quite a while and your map compelled me to make the effort to at least give it a go on Hallowe'en evening. Perhaps having your full map available took away some of the mystery and fear, and Bobby the Scissor Man only had time to attack me twice (excluding the final confrontation), but, not that it's the best excuse, I wanted to play it in one sitting and get at least one decent ending within that Hallowe'en evening/night instead of spending much of that time wandering in and out of rooms. Jennifer isn't exactly quick on her feet so that would feel more like wasting time than any sort of meaningful experience. Or maybe I just have a short attention span and limited patience...
I got the best ending on the first and only try, and I'm sure a lot of it has to do with your map. I did die a few times along the way, however it was not by Scissor Man, but by the stupid bird...
Anyway, I probably wouldn't have really made time to play this game in the first place if not for the map, let alone getting through it, with the best ending to boot, so if anything, it has at least been of benefit to me. Thanks!
