Looking for the Being One series again after nearly a decade and finding this and episode 5, I had to buy it just to soothe my nostalgia! While episode 6 feels a little dull compared to the previous ones, in large part due to the fact that the creepy claustrophobic feels now missing, it's great to hear you're still working on this series.
Although the FPEG style is interesting, I think it might be a better idea to return to the point and click formula, especially for games which are trying to be creepy. Regardless, I look forward to seeing what you put out in the future!
