Fullscreen no longer necessary.
Still recommended.

Have edited my original comment to reflect this change.
Thank you for the explanation, and having played to lose, I can see that I did misunderstand what was happening the first time around. I think the UI could maybe have indicated this clearer, but I think it also falls on me to have read and understood better.
Like another commenter said, the background texture negatively impacts the game. Personally, I would have considered either black or maybe a shade of blue, to make it less challenging on the eyes.
Best of luck with the ratings!
