question about this VN

[KittyLove01-TTV]

So I got this VN but I thought it was locked into a small screen and I have horrible eye sight, because of that I refunded the game (reason being I can't see the tiny font/words due to it being in a small screen.) My friend that has played a fair share of VN games on steam (I played in nintendo but recently got a PC, so I'm new to steam.) said that going into options and making the screen "full" is an option in most VN games. I'm worried that if I buy this again after I just got it refunded, learning it doesn't have that in options and then being stuck with something I can't read will happen. So my question is does it have a Full Screen Option in the setting menu and if it does can someone tell me. I was very disappointed when I couldn't read it but now I need to verify that this will work before I buy again. Thanks to anyone that can help answer my question.
