I don't quite recall the SFX in 6.1 (good sign?), but my general stance on sound effects is that between bad effects and no effects, the latter is preferable. I remember dropping a game because of the dev just poorly recording himself sucking spit through his teeth and mixing that into the only audio channel. That was not only gross, it was insulting to think the players wouldn't know the difference. The game had other flaws, but that was the final straw.
Just make sure the effects are somewhat realistic, not too exaggerated or gross, and timed properly. Less is more, accuracy matters. Keeping music, voices, and SFX in separate audio channels with their own volume sliders will keep you safe no matter what, so I highly recommend it.
Hmmm... If 0.8 is closing two of three (or more) chapters, I guess we will get to see the 0.10 at some point? Hah, I'm looking forward to see the reaction of those who don't know how version numbers work. Gonna be fun. ^^
