1-bit in motion

These look good, but are all in .gif format. If you're using e.g. godot, you'll have to first convert these to spritesheets and individually pick out animation frames for each animation. Animations seem to be 15x15 pixels, have a margin of 30 pixels from the border of the gif, and 15 pixels between each pair of sprites, making this very inconvenient to use for my case (I think I'll just take the loss and use a different sprite sheet). For $5 I would have hoped for a directory structure like sprites > cats_and_dogs > yappy_dog.png, with yappy_dog.png having just the four sprite frames. Or at least a sprite sheet animals.png with consistent margins where I then have to pick out each pair of frames and convert to a single animation.

tks man...I'll use it in a Game Jam!

Can I use this in a game jam and/or commercial use? 
I only need to give you credit in game credits?

Hey! Wondering if you'd be open to commissions

These are pretty great, they have that old Macintosh point and click feel to them.  Are there some frames missing in the sprite sheet?  The gif preview seems to have more for the eyes.
