Most of us are able to use GIMP (for example) to replace magenta with alpha. However, it's not only tedious, an alpha channel can do much more. E.g. parts of the spaceship could be made partially transparent."
1) A non-transparent background on pixel art is sometimes easier to deal with for later manipulation by another artist.
2) It can indeed be tedius, and I don't want to spend a lot of time providing different formats of the same sprites to make things extra-easy for every possible project. If you want to use the assets, do it yourself.
"
Don't provide different rotations of the same image
It's much more difficult for us to pick the correct sub-image at runtime than rotating the image on-the-fly. Programmers who don't know how to rotate an image are very beginners and still have much to learn. They should not learn how to pick the most fitting image. Loading a big texture consumes more memory and it still doesn't rotate that smoothly. We only need the image with the ship pointing to the right."
Dynamic rotation of pixel art assets is a very bad idea. Rotations have to be manually cleaned up to avoid looking awful (just see Pokemon Black/White's animated pokemon; it's really jagged and bad). In other cases it might be less of a big deal, but it's never going to look as good as it would be if it were pre-rendered.
The example isn't actually so bad, but you get the idea. You can't rotate an image that has light coming in from the side. Imagine how it would look like if two such ships were adjacent to each other, but point in opposite directions. You should light your 2D objects from above, for example."
Sorry, but this is just silly. While having light directly from above is convenient for some top-down shooters, in general it is poor practise. Non-directional lighting doesn't do much to reveal forms and tends to be visually boring.
Personally, I would be all about the feelies. I would very much like a shirt, maybe a mug. I already have a nice themed mousepad, but I could always use another (since I carry my mouse everywhere with my laptop; touchpads are for chumps.) (That said, the custom mousepad cost me a buck on a special deal).
@cdoty: yeah, they could use some more animations to be a bit more widely useful--I've just got too many other things to deal with at the moment to add more unpaid work on top of it.
@Zabin: awesome! Animated sprites would definitely be an interesting addition.
@TheValar: As Surt said it's in the included files, just not part of the previews. It is unfortunately not seamless (since that wasn't a concern for its intended use). I don't think it would be too hard to make it work, but it would take time.
@surt: Thanks
@Vestrel00: Thanks!
@Sir: Yup, so it goes. I'm glad that OGA provides a venue to make it possible to do that.
One thing I'd like is user tiers/titles displayed under usernames for various accomplishments. I think that this tends to speak to people more than things like medals, fun as those are.
OK, after having discussed it on the IRC: yes, each author does need to be included in the attribution instructions. So Daniel's submission is in error on that point, but don't worry about it. Just be sure to include him, and include me if you'd like.
Actually... I might be wrong. I don't think I am, but--I have been assuming the credit on CC-By is 'viral' (that is, all subsequent derivatives must be credited) but I'll need to discuss it a bit on the IRC to be sure.
Oh, sorry, one other quick note: your attribution instructions do need to include Daniel Seigmund, as specified in his upload. I'm not mentioned in his attribution instructions, but since it's an official commission based on another official commission I don't see that as an issue.
I gotta say, it's really neat to see a third-generation iteration of those wall tiles. I like what you've done, and I also appreciate anyone expanding an existing tileset.
See, the thing is, what he did there wasn't mere jerkishness. It was an outright violation of the licensing of the asset (that is, illegal). It is up to the artist (or their authorized representatives) to pursue legal action, but if the stolen assets are being hosted on a venue like that generally the admins of the hosting will take care of it if proof is provided.
Re: modifications. If it's freely licensed, making changes to an asset shouldn't be a problem. If it's not freely licensed, I'd make sure it's fine with the artist first. Best to have very clear communication on those things if you don't have the license to clearly define what's allowed (heck, even if it's licensed it's nice to ask even though it's not mandatory).

(edit: yeah, Duion beat me to it.)
They can't exactly stamp their name over it, in that they have to continue crediting the original author no matter what.
