Everything expect for the size of font is good. The font size is size 4 if of microsoft word. There's no reason for a person to increase their zoom option on their browser all the way up just to read. The characters background and other information are the same font size no way to read it without hurting one eyes. I feel the font size was rush or not thought of properly to whom they're addressing it to. In order to play this game a person has to read.
If the font size is too small try making it readable so everyone can enjoy. Try find some how if it's a problem to increase the size or find out the problem that cause it. It can be tricky so good luck! =)
