You can do it! :P
Putting your browser in "Desktop mode" could maybe help.
i tried that out because i thought that was genius! i hadnt tried that previously, n booted up the game again excitedly,,,sadly, desktop mode, vertical and horizontal both don't work due to the lack of slider on the popup textbox; the textbox just follows in the same stuck position when i try to scroll to read it, and the words at the bottom (including the ability to close it) remain cut off :'D thank you anyway! hopefully ill get a PC sooner than later!
