Edit: The game-breaking bug I mention below seems to have stopped occurring for me, but I dunno why!

Hey there! Love this! Have very much been missing this feature. And the added colour change and high score are great! Got two notes: One is that the game seems to break after every loss, and the page needs to be refreshed. After that point, the "apple" dots you're trying to eat just phase through the snake and cannot be collected. My other note is that I'd like to be able to re-bind the controls, specifically, I want to be able to activate the game with the up arrow and play with the arrow keys. (I know this clashes with scrubbing and volume shortcuts built into YouTube now, but those can be disabled with other extensions.)

Also, less of a priority, but it isn't compatible with PlayerTube. Would love to be able to play snake in combination with era-appropriate YouTube player UI!

Great project! Hope you can fix whatever's causing the apple bug!
