Not colorblind friendly

This is a really cool and well made game. However I am unable to successfully play it because it is color coded to blue and purple. Which are the same color to me because I am colorblind. Please developers at least make an option to at least change the colors if not reset the default. Thank you.

Developer Response ,

Thank you for your review. We will surely support the colorblind mode in future and inform you.
