Since getting to a snake-food faster means getting more points for it, I always play on python, which is why most of my scores are crap except for a few that are in the 1 or 2 thousands. One technique that helps is pressing two arrow keys in rapid succession to adjust your heading by one block, because when I turn in the direction of another snake-food thing I'm sometimes off by one. And if a snake-food pops up next to a wall, I time it so that I might turn too early (better too early than too late). If I turn too early, I can use the adjust-by-one trick or go past it and do a really fast u-turn. If it's in a corner, then I just pray.
