Are you sure you've downloaded the correct version? I can replicate this only on the older one. Admittedly, it's easy to miss, because it's just a difference between v0.1 and  v1.0 at the end.

(edit: The older version should be disabled now.)

Yes, the texts are unfortunately unpolished. We barely managed to add them all and we didn't have time  to fix them up before the deadline.

And yes, we made a very simple powerpoint engine for the game. (If you're interested in some details: We designed a simple scene format on top of JSON, and then with the help of a few libraries, mainly SFML, we needed to make that scene format display something on screen.)
