Neon Serpent

Neon Serpent is a Snake game on a 20x20 grid. It has a glowing neon look with trail afterglow and smooth animation between grid ticks. The rules are the classic ones. Guide the serpent across the grid, eat energy orbs to grow, and end the run when your head touches your own tail or the arena wall.

Scoring scales with the snake's current length. Each orb is worth 10 base points plus the number of body segments you have at the time. A short snake scores modestly. A long snake in the mid-game multiplies each pickup a lot. Speed starts at a 150ms tick interval and drops by 2ms per orb you eat. It bottoms out at 60ms, which is about 2.5 times the starting pace. There are no bonus orbs or obstacle walls. The only growing threat is your own tail.

You start with 3 segments. On mobile, you use on-screen directional buttons or swipe controls with a 30-pixel threshold. When you die, a red flash appears. A 1.2-second fade follows before the score screen shows up. That pause lets you see where the run went wrong before your next attempt.

Snake is older than most people think. The core idea of a growing line that must avoid its own tail appeared in the 1976 arcade game Blockade by Gremlin Industries. A two-player version ran in arcades through the late 1970s. The format stayed popular as a programming exercise through the 1980s. But it hit mass culture when Nokia bundled a Snake game on the Nokia 6110 in 1997. By the time the Nokia 3310 shipped, Snake had reached hundreds of millions of players.

Smartphones briefly made Snake awkward to play since touchscreens didn't fit the original controls well. But the format adapted. Swipe-based controls became standard, and speed-based versions explored mechanics the original grid never could. Neon Serpent adds length-scaled scoring that the Nokia original didn't have. Eating early orbs with a short snake scores less. Threading a longer snake carefully to collect orbs in sequence scores much more.
