Yeah! Another Godoter!
First off the art is really good! The chicken is cute and the upgrades make it cuter! The sounds and music are good too! The concept isn't too bad either. I half thought of doing something similar.
My only negative feedback is that I never got very far from the ledge. And I really tried to flap fast with the spacebar. Maybe each flap should propel the chicken further?
I also noticed that the move forward key was "D". Seems like we have a WASD fan here. Well, I would suggest always supporting the matching arrows keys too for those that are left handed. It's easy to do in Godot in the input mappings.
