It would be nice to add more preview images. Because it's in a zip file you have to download and unzip it to even look at it.

If you really want download count, you can put individual image files alongside the zip file - then they can be viewed in a browser by "open in new tab", and it still counts as a download.

I'd recommend more tags too.

Or make the main preview file into a gif showing all the animations. :)

-In my pure opinion, making a .gif is a privilege, because is time consuming option, and user have to had some experience with it. But it is not bad if .gif is optimized which is an extra bonus in this whole picture.

For simple animations it is very quick to make a gif from gimp! This is with 2.8.14:

1. Paste the first frame as a new image

2. "Paste as New Layer" each of the rest of the frames

3. If it's pixel art at retro resolutions, and the gif is for previewing or demoing and not for direct use in an engine, then scale the whole image by a factor of 200%-800% without filtering

4. "Export As" and put a .gif extension to the filename, accept

5. Dialog pops up, select the "as animation" tickbox and set desired frame rate (in ms/frame: so 50 means 20fps, which is about the fastest that you can expect browsers to display it reliably). You probably also want to tick the "repeat forever" and "replace every frame" options

6. Accept and done.
