So, I have been a video game journalist for console games almost 20 years now and a pc technician for longer than that. Finding bugs is what I do for a living, quite literally. I fully understand how it is expected during the development prossess and even shortly after release, so don't sweat it. I am OCD (most techies and programmers are) so, I understand and relate to your feeling of annoyance at missing bugs. But, remember, the upside is you work for yourself and e only deadlines you have are yur own so don't sweat it. You are doing a great job and have a game that is fun, has amazing art, and a pretty decent story that keeps us wanting more and guessing what is happening next. Even if this was not an adult themed game I would still play it just for the art, story, and feel of classic point n clicks like Discworld that this gives off.
TLDR: keep up the great work! LOL
