I liked how the movement and jumping felt, but couldn't get past the first screen where you see the roof of the barn, so I'm not sure how much more there is after that :D
I think I had difficulty seeing how the amount of rooster squish related to the power of the jump, I don't know if it was just my eyes playing tricks, or if it wasn't directly linear from squish amount to jump power, but it felt like it was making it harder to gauge any jump that wasn't full power.
The rooster theming is nice but I think I would have liked ifmore had been done with working the theme into the gameplay. It feels like this game could have any assets attached to it and it would fit any theme as well.
Great job with the game!
