Thank you for your reply and support. I apologize for any inconvenience I may have caused you. I tried to refresh the game a few times again, and I discovered that it is a random issue. Sometimes the word did not light up and a few more clicks would turn the screen with a red layer, and one more click would return to normal (but the word still did not light up).
I think it might be related to the website button in the upper left corner of itch.io. When I click the geme option near it, the game does not respond and the screen turns red. I don’t think it is your fault, but maybe some glitch in the game engine. Apologize again.
