First, I want to say that making a game that runs without an OS is just brilliant. The only way it could be more ingenious is if it included a bootloader, but that wouldn't fit in such a small space.
I did not enjoy this game. Not that it's bad, but the dev has taken the classic snake game and made it where you steer the snake, which is frustratingly difficult. Props for sticking to the limitation, but this may not have been the best choice of game for that. Further, J/L rather than A/D or arrow keys is such an odd choice. Alternative controls would have been just fine, rule-wise, and perhaps made it easier for me to adjust to. In the end, I couldn't.
Still, I love retro games, and snake is a classic.
