Nice game! I liked to feed the duck, especially on how it grew each time I fed him ^^
Unfortunately, I couldn't find the last meat for the duck, and I died, so I lost all my progress, it was quite frustrating.
However, I enjoyed well the gameplay with the sword, for me the only thing that you can improve on it, it is the mouse lock which is disabled for the moment. Indeed, a lot of time I hit elsewhere on my Window, so with a mouse lock, it would fix this little issue.
Overall gg for your work!
