I know right? He probably has double the renders of the preview version. Double the amazingness in only 7 months, outstanding.
It's amazing how those people who get it for free, and probably don't get the progress updates, bitch and moan and those people that do get the development updates don't.
However, for a brief overview of the last 7 months.
1) He's had a contractor who was meant to do some of the work on the mobile phone and computer bit run off with the cash so he's had to do it himself
2) He's moved office due to issues with a landlord misleading him about the internet connection strength in the last place he had. Meant he had to find somewhere new, set it all up, put in AC as the machines were overheating in the new place which took time to sort. He also had electrician's in to do re-wire and had the place decorated
3) As part of doing the last part of setting up his office he had a very large and very unfortunate accident with a hot glue gun, meaning he burnt his hands and fingers the point he wasn't able to do much actual work for a few months
4) He has done a complete re-do on the walkthrough, which will then be implemented into the game itself and not as a stand alone
5) In response to some of the criticism above, update 17 will include new content for all the major LI's and a few of the minor ones. I think he indicated that, depending on the routes and girls you have active, there are 6 different girls you can invite to the summer party.
He was transparent about the lot, gave people the knowledge they needed to stop paying when he stopped working if they wanted to. Told them when he had recovered so he could crack back on.
