The only way to save MP is to hire good coders - doesn't matter whether Ren'Py or Unity!
I haven't played this one (yet) so i can't really judge about the game itself.
But based on your opinion and many others the coding really sucks and he should hire new Coders.
Now the main question that pops in my head is.
How did he hire these guys in the first place ? .
Logically with a project of this size and the money that goes with it you would assume that there would have been some kind of "test".
But it seems like he just hired some guys he knew based on promises.
A friend of me that is working on a project for the last 12 months wanted to hire some coders to, so when he got some replies of people that wanted to help him he asked for a short tech-demo that proved their skill level
All except one didn't reply back, and that one that did reply back came with multiple excuses over the course of 2 months why he couldn't do it.
So he decided to just do it himself, that way he knew what he would get... Even though he wasn't the "best" at it
Honestly, when i see people on this site saying that they want to help with things like coding or rendering i feel like 95% of those people only want to be a part of a project even if they have 0% skill.
And i feel like Lewdlab fel for that exact trap.
So i hope that for his future project he will be more careful and strict in hiring new people.
But i am going way more off-conversation then i wanted to.
I liked Dreams of Desire, wasn't my favorite because everything moved way to fast for my taste(but that's personal preference)
Renders of Midnight Paradise look amazing, but (based on the renders only)i really didn't see one character "pop" out for me yet.
Wanted to try this game at 0.2, but it seems that it's better to wait for couple updates more.
Shame, but Lewdlab proved he can make a solid game with DoD...
So for now he gets the benefit of doubt from me and he will keep getting my pledge as the last 2 years before that, but will not hesitate in dropping that if these problems go on in the next months.
