As far as I can remember, LienPixels, yes, you technically can make all of your own aspects like you normally do and change the aspect ratio to a 2x1 pixel-ratio format... but there are definitely some significant risks to this, in that some sprites can look too stretched that they sometimes end up looking more needlessly squished and awkward to use. I mean, I’ve even had that happen myself numerous times when I first began creating my sprites in this format from well just over a year ago... even when I tried to make a normal 1x1 pixel-ratio styled sprite into a 2x1 one at first. But rather then, using this quite interestingly fascinating new method that I am gonna show you here right now at:
...you and I can finally craft and design much better and more coherent game sprites to perfectly fit in a 2x1 pixel-aspect ratio that clearly works. I mean, I just love to inspire such awesome and wonderful people like you indeed in order to help us improve much more richly as we learn along together, all of us!!! ;)
Great to have you with us as well, and welcome to my Wide-Dot Pixel Game Jam 2017 indeed!!!
