Acknowledgements & Third-Party Licences
Last updated: 23 August 2026
Barnyard Breakout is handcrafted by a very small team, and it stands on the shoulders of some remarkably generous creators. This page is the canonical home for every third-party credit and licence notice in the Game. It is linked directly from Settings → About & Legal in the app, and we keep it current as the Game grows.
If you believe an attribution is missing or incorrect, please tell us at contact@barnyardbreakout.com and we will fix it.
The cast: thank you, Kenney
Every single playable character in Barnyard Breakout (all twenty-four of them) comes from Kenney, the one-person asset studio whose free, public-domain art has quietly powered thousands of games. The bunny you launch, and the beaver, bee, cat, caterpillar, chick, cow, crab, deer, dog, elephant, fish, fox, giraffe, hog, koala, lion, monkey, panda, parrot, penguin, pig, polar bear, and tiger who fly beside it, are Kenney's Cube Pets models, dressed up in our cel-shaded look.
Kenney's work in the Game:
- Cube Pets: the entire playable cast
- Nature Kit: trees, bushes, grass, mushrooms, and flowers across the world
- Food Kit: the carrot pickup
- Mobile Controls: touch-control iconography
Kenney releases everything under CC0 1.0: free for any use, no credit required. We are crediting anyway, loudly, because Barnyard Breakout simply would not exist in this form without that generosity.
If you make games (or want to), visit kenney.nl and see what one extraordinarily generous person can do. And if his work helps you the way it helped us, consider supporting him.
Models & environment art
The world of Barnyard Breakout is a patchwork of open art and our own work. Where a licence requires attribution, it is listed in full below; where it doesn't, we list it anyway.
