Low Resolution Map Rendering

[asanme]

Hi,

I've been using this library for the past few days, and I've been wondering if there's any way to increase the resolution of the rendered map. I'm using a world map with GeoJson but when the map is fully rendered it appears blurry and very low quality. I've searched through the library's files to find something related to the vector simplification or something along those lines and have also tried modifying the library directly, but I can't seem to get any good results.
Is there any way to prevent vector simplification or render a higher resolution map?
Here's the output of my project:
