Oops. That's not good. Never seen that happen. Was the text there at some point and then it disappeared? What browser and OS are you using?
Thanks for the detail. Have you tried the game again since your initial post? I released a new build on April 13th that may fix some of the reported issues.
BTW I just tested the game on Windows 10 and Firefox and while I didn't encounter the text disappearing bug, I did notice that the game was running noticeably worse on Firefox (I had a direct comparison with Chrome running side by side).
