Weird PNG?!

The webp image format was created for web use mostly, to decrease the loading times & bandwidth usage of websites. VS allowed the format I guess because the images / animation frames will load faster & require much less hard drive space overall in comparison to jpg or png.

Jpg doesn't always seem to display correctly in VS for some reason. Png usually displays correctly except in certain cases where the image mode / settings were not correct during creation / export.

Personally for me the png format can end up quite large in size for each image due to the lossless format, which isn't really all that good for 2D & people that don't have decent computers. For example: during certain parts of the game I'm working on, I had quite a few animations on the screen at the same time that were all png & my laptop (which is more than capable enough of running pretty much all VS made games) was lagging at times, until I replaced all the images & animations with webp, then it was smooth sailing - not to say that that would be the case for everyone else, as it's all down to what your computer can handle.

Anyway, I believe that programs will more likely than not add support for webp, at some point in the future, providing webp continues to grow. Photoshop already has third party support via a plugin as far as I know & there are probably other programs which have support or the ability to convert to or from webp.

webp is way superior to many other formats, it compresses better than jpeg with less artifacts and has also alpha channel support. There is no format that can do that. Png only supports lossless, generating very big images, even if unneeded. Webp is the perfect choice for these kind of adventures where you have lot of images and want it to be small, but still look good and support alpha channel. Btw. here's some stuff about Daedalic porting to mobile: http://www.makinggames.biz/features/from-mouse-to-finger-adv...
That platform profits heavily from small image sizes, reducing load times.

That was a a pretty interesting read, with some useful tips in regards to mobile platform releases & sales marketing. I too prefer to wait for sales (steam) etc as it's much cheaper, but I believe that sales are good because not everyone can afford to splash out on the original price tag, thus it's possible they could potentially make more money through games on sale, than in general sales of the RRP.
