Final Sentence Demo

I'm playing a demo of a typing challenge game called final sentence.
It definitely has a unique twist to it.
It's an online battle royal, player versus player type of game.
Unfortunately I'll need more from a demo to consider a future purchase.
Not very much too it.
First case I've come across where upgrading the player level does absolutely nothing.
I'm going with 1 star out of 5 on this one.
