The PC version is absolutely sublime and allows for a larger playfield and it's possible to zoom out and play with the entire island visible on screen. There's support for high refresh rates and it works perfectly on my 240hz display. Also various QoL changes and subtle lighting effects to enhance the look. The file came with the source code and should be easily moddable.
