Thanks for your comment dude. You will be surprised, I have never played Typing of the Dead. So, without checking on the internet, I think the game was on the Sega Dreamcast? Believe me, where I come from, the Dreamcast was only for very very very rich people when it came out
. just memories. It's funny because, nowadays, I'm sure I can buy one at 60 bucks or less.
For your issue, it should be fixed now. It was caused because the font I used in the game is not installed on your computer. Therefore, the Word "Back" in the tutorial screen is present but it's not visible because its width is too small. Let me know if you can see the word now.
