I'm sorry, but I can play it normally on my computer. By the way, do you use Windows? Did you launch the game from the "Game" app above the Zip file labeled "Game"? If you meet these, I'm not sure what caused that bug.
I use windows 11. I try with itch launcher and download it from the page unzip it.
Same error happen on both instance see the protagonist well... I'm kind of sleepy then that img/characters/%E7%A5%9E%E3%80%80%E6%AD%A9%E8%A1%8C.png pop up and clicking retry don't seem to work.
Both version lock at same point too even the save with non english version with 56s trigger same error too.
