I finally got around to properly starting a vn.
After wasting a lot of time searching for god knows what, I ended up downloading Demonbane.
Just played through the prologue and it definitely seems promising.
I had read somewhere that there is a lot of problem regarding the voices and that a patch exists for that. I have the Jast version, and the place I downloaded it from didn't say if it's pre-patched or not, so it would be great if someone could tell about the voices patch.
Another thing I noticed is that the game crashes if you try to skip a lot, it shouldn't be much of a problem though.
