He worked as an artist in game development before.Look, not wanting to detract from your opinion, but the fact that the game is practically free weighs a little in terms of the fact that the biggest criticism regarding this is the delay in updates.
Let's look at the facts.
Darkcookie as far as I remember didn't do any art or college of any kind (at least he never commented on the streams) He learned by doing, his team is also made up of people of similar caliber, and given that each of them must have their reasons to continue in the project, some dev's have their own work and do a kind of help for Dark.
He has his family himself, so the time he spends developing the game is limited.
But even so, I believe it delays certain points on purpose... I'm a programmer and I tell you, it's not that difficult to write lines of code for a game like SummertimeSaga, I've already messed with some game files myself to see what I found over there (I know, I do this with every game, kind of a habit like I'm looking for something that doesn't exist)
But, everyone has their own opinion. But both sides have strong arguments.
The thing he had no prior knowledge was coding, hence why he started with Summertime Saga and one of the big reasons the code is messed up. Alongside quite a few switches in between the coders along the way.
As a programmer you should know how difficult it can be to get into someones mess without clear descriptions etc.
Even worse when there is/was more than one person who worked on different portions of it.
Different styles, different usage of code,variables, operators and many more factors.
There's like zero reason for him to delay it. No monthly goals or promised updates.
It's also not like he doesn't want it to end. He already mentioned planning and putting some thoughts into concepts of a new game once Summertime Saga is finished.
I think he'll use that experience on the next game regarding planning, starting the entire process etc. so he won't make the same mistakes again.
There are some factors that deserve valid criticism, but the majority of shit that gets thrown at the wall here is nauseating.
People really need to get back to stuff once it's done. It's a lot more healthy than to waste their time with being angry, for not being able to wank to a certain game for a while.
There's plenty of porn and/or game alternatives out there. It's a niche thats attracting some unecessary angry people for whatever reason.
