Enhancement: Proper week 6 resolution

Please check for duplicates or similar issues before creating this issue.

What is your suggestion, and why should it be implemented?

As a pixel artist week 6 is pretty cool
except
MIXELS NOOO WHY HERE

Week 6 uses pixel art graphics for its assets but the actual game isn't at a resolution where an asset pixel is the same size as an actual game pixel so when a sprite moves it creates mixels. I don't know how easily you can change the resolution but if there was some limit for week 6 that would look alot better imo

(also could you maybe resize the hold arrow lines to be a bit thicker please i scream in fear whenever i see them)
