I really hate piling on... but this is actually a joke. Legit only see these scenarios happening (from most likely to least likely):
1) There was no update, there was no work, just false promises.
2) Another delay (most likely didn't develop anything so far)
3) Oh no, my computer crashed, but I'll be able to recover it jus need to delay it.
4) Oh no, my computer crashed and a lightning hit my house, all the work except for the things I had in latest update were lost, but don't worry at least now I know what I wanted to develop so it won't take as much time.
5) Sorry been to the hospital because I/My mom/My dad got into the hospital or my fish almost drowned, update will come out after I get back home (it won't).
6) There is an update and it's nowhere near enough considering the time it took.
...
100000000000) There is an actual update and it was worth it all along.
I bet I'll come back in a week, or a month or a year and be right about one of the above, whenever the dev decides to talk, which probably he might not even do that and just go missing, collecting whatever people continue donating over time. The circle repeats itself time and time again and the excuses are always the same, the process of promises is always the same... Blegh.
