Thanks for your feedback!
I just played it myself and I can agree that the speed is way too fast. But it really shouldn't be this fast. I sped up movement late in development after getting feedback that the player was too slow, but then it seems to have been missed that the player was now way too fast. After reading your comment, I'm now wondering if the initial speed would have worked fine, but just feeling to too slow because of the heavy difference when carrying a parcel.
