There are a few interesting things going on in regards to the structure, but probably not enough to justify actually reading everything.
For the most part, this is just fanservice for people looking for more interactions with the Tsukihime cast. Some of the little side-stories are nice but most of them are just ok. I guess if you're really desperate for more Tsukihime then it may be worth it but I don't think the vast majority of people are actually going to find enough content to justify the time spent on this game.
A much bigger issue is with the structure itself. While interesting, many aspects were poorly handled. There's a huge focus on repetition but the skip function is poorly suited to showing off smaller changes that occur. Rely on it too much and you may miss interesting or important details, use it too sparingly and you're gonna have to reread a lot just in case there's something new. Both options are quite flawed.
Additionally, the game can be a bit obtuse in regards to progression. You may be missing a single scene needed to proceed in the main story but have no clear idea how to obtain it without consulting a guide. Major plot points might be behind choices which used to be unimportant and only later gained value (with this being poorly telegraphed most of the time). But sticking with a guide the whole way through isn't ideal either since the exploratory structure of the game is one of its main strengths, something which is lost if you just let the guide dictate all your choices ahead of time.
Kagetsu Tohya has some neat things going on, but I don't think its strengths are sufficient to justify a recommendation. It's still alright and, if you really love Tsukihime, you may still find a lot to like in the writing here. But that just wasn't enough for my tastes.
