cool game, but honestly, I feel it would have been better if the duck wildcard had not been used. the duck shaped vehicle and sounds... kind of broke the immersion and tone of the game which was good imho, especially because of the music.
Loved the variety of enemy types but I had the impression that the player needs pre existing experience with that type of games. It was not clear to me until after the first runthrough which enemy type does what. Too many variables hit you right from the beginning.
Oh and a retry button would be a nice quick win. I had to redo the keybinds on every start....
