Good sound design, and catchy music! Controls pretty well.
The boss fight was actually really fun. It reminded me of Thexder 95, of all things. (I hope someone reading this comment knows what that is lol)
If I have one criticism it's that the sprite work is inconsistent in quality.
Some of it looks great, like the house, the boss, and the cutscenes. But some of it looks lazy or ugly. Like the platforms, and the main duck character.
Overall a solid entry. Good job! :)
