I don't know what proposital means, but the text or the background shouldn't be white. Maybe try reloading or maybe I could try helping you at some point. (I might know what it means now).
If you can't get it to work on your computer, here's what you can do. Go to the link on your phone, put it sideways, click run game, and set the zoom to 50% or something like that. The game isn't optimized for mobile, so the screen won't be centralized, but in theory the game might run fine.
