What do you mean? Dynamic lighting is already part of GD. The fact that it's native-only doesn't change this.
I was referring to HTML5 platform. It doesn't have it, even a fake that only blend layers and sprites would be nice but not even a fake is possible. I know you don't care for HTML5 but it doesn't change that I do.
Also fluid simulation could be faked reasonably well with a lot of small circular Box2d rigid bodies
Yes but without blending the sprites it is going to be nothing but a pool of balls, GD currently does not support blending sprites.
As for networking, it's best to leave it to the devs, providing ability to call REST APIs on the web and create raw TCP/UDP sockets.
Online multiplayer games also need a server which is very expensive and big commitment. This is what PlayerIO provide along with an easy way to add in-game purchase which is pretty much essential these days in any online game.
But it does not exclude to also add features to create raw TCP/UDP sockets...
I see a contradiction here. "Offering paid version, but with more features" would essentially make free GD a demo,
Yes in a sense but there would be no time limit, no limitations on export, no limitation on number of events, number of sprites..etc There would be no limitations as such only certain features would be not included which is not necessarily downgrade it to be only a demo. Full source would be also available which is definitely something you can not see with any demos out there.
Again, you can't know whether patreon would work for GD or not until you'll try it.
Of course I don't. It up to 4ian to try but remember that donation was already an option since day 1. If anyone did want to donate could already do so but obviously it was not happening regularly so why Patreon would be different? Patreon is nothing but a solution to offer regular donation, but it is require regular donations which have been already possible with PayPal if anyone was interested, earlier versions of GD4 was even popped up a message time to time to ask for donation. Patreon on it own would change not much. All I'm saying, I don't personally expect success with donations but again, it up to 4ian.
Either it going to be donation, monthly subscription to online services or Pro license or the mix of all this, I be happy as long it allow GD to be developed in full time and see new features coming regularly.
