I play Lexulous on my android. I also have issues with vision sometimes.
The scores at the top are white on light blue and it's difficult to see this.
Please give the option of changing font colors on the board and the tiles.
Thank you.

@lusciousgrape very true. I frequently get all vowels or all consonants. I had one game that had 5 Is or 5 Os. It can be quite annoying.

Tried to use word BIGA, and a pop-up says it wasn't a legal word in America.
I found it on 3 dictionary sites.
