well maybe this will be helpful to you.
It is very much worth a couple playthroughs. Cece and Lexi's & Lexi+Holy's story paths are very much worth playing through. Their stories are very well written. The story begin to drop in the sense of feeling not fully thought out with the rest of characters near the ending (still worth playing them imho. But you won't experience much in terms of "wow factor").
So, if you think you can go through at least 2 playthroughs maybe 3 if you're missing either the Lexi+holy combo story, or if you did that one and just missing Lexi solo (not much difference between those 2 in terms of story, perhaps some dialogs etc), then it's very worth it. So 2 times would be more than enough if you typically get tired of that style of game.
It's entirely up to you of course. But I recommend the VN for it's story richness, it will make you laugh, shock and gut punch you. I could go on and on about which story path is still worth playing or not, but this isn't the thread for it anyhow.
I hope you decide to try it because Drifty really flexed his creative muscles and earned a lot of points as a creator with that VN.
