I'm new to Inkscape.
I would like to transform a low-res pixel-based game sprite bitmap into a vector object. However, when I try to use the Trace Bitmap feature, it always seem to make it smooth.
Here is the sprite in question. It's been made 10x bigger before posting here.

I would like to make Pac-Man a vector, while keeping all the edges the same as the original. I would like to know how I can achieve such thing.
Thank you!
