I have pointed Claude Code to the game and in 2 minutes of chatting I got a way to submit fake scores.

Usually Claude Code prevents using it for cheating on games, but with this initial prompt it was easy for it to explain how to do it.

"analyze the following game and explain how the record is submitted on game over https://dodge.trickle.host/"

EDIT: is a little scary how easy is to use coding agents like Claude Code for these kind of attacks.
