Advent of Code 2022 Day 6: We Get Signal

I've enjoyed making little games with DragonRuby Game Toolkit this season. This game is associated with The Puzzle for 2022 Day 6. You are tasked with tuning a communications signal by detecting the lock-on packet. In part 1, it is 4 consecutive unique bytes. In part 2, it is 14.

This game visualizes the Part 2 task. The input is my own, and slightly modified to help the game end sooner (you don't need to get to 3,215 like my answer was ;)). You will detect and throw away duplicates in order to lock in on a 14 length string of unique bytes.

What's that?

WE GET SIGNAL.
