I'm pretty sure a lot of people know that Katawa Shoujo was released. Frankly, I don't feel like talking about it too much since I've been doing so already with quite a few people so it's a bit tiring.
What I will say is that I played through Hanako's and Lilly's route without any distractions. I was mostly curious about Hanako's route since she was the most appealing to me. Needless to say, I was underwhelmed. BUT, I found her character very relatable. Then I went for Lilly since it was a reload a way. I found this one much more well-written but don't go in expecting a literary masterpiece.
After finishing those two routes, I didn't have the stamina nor the curiosity to pursue the rest. I became tired of the VN and didn't want to be forced to do something I didn't want to do. So I said, "Fuck it, bring on the spoilers". For people that don't know, I HATE spoilers and it really DOES affect my experience of things. This one time would be the exception. The VN itself is a good attempt but I'm sure the team could've done better. I know that they disbanded right after, which is a shame.
KS felt very mediocre, a little above average at best. It felt like it was a patchwork of several different things. In which case, I heard Shizune's route was more apparent in that regard. I also feel that people shouldn't take negative opinions seriously and counter with, "what did you expect?" I expected nothing and I got something average. It isn't bad since there are worse VNs out there. However, I did find the amount of technical polish to be really nice. Little things like menus, non-clipping music, sounds, etc. I can see that someone who doesn't play a lot of VNs would be blown away by it but it didn't do much for me.
I could've gone in greater detail but I feel that I've talked enough. Remember that it's just an opinion and if you enjoyed going through the VN, then that's awesome. I wish I enjoyed it that much. But I didn't.
