good idea for game to have dual-duck-gameplay! Cute artstyle and calm music! Though my speakers started to crackle for some reason and game started to lag behind after a while. Are you instantiating nodes more and more that are not deleted of what is happening? Then the game just crashed on the second level.
I like the intro. maybe add some sounds there. may not need a text even as it is somewhat self-explanatory.
Good job!
