At first I thought (like most of the other commentators here, I guess) that the game is quite slow, but when I noticed in my second try that the "Add sugar" button is there and fully functional... Oh boy, that was just great! You give every player the chance to increase the difficulty level as they please, and that's just when the retro highscore vibe intensifies. :D You nailed the whole Game-and-Watch aesthetic so perfectly as well, that's some really great work! That's why I recommended your game along with three other jam submissions in our COFFEE JAM compilation article, and put one minute of gameplay into the accompanying video. :)
Do not be seduced by the sugar cubes, dear strangers, because there is only the Black Coffee God!
Best wishes,
