Serpy

Serpy is a serpent — serpent, as in snake, as in… this is a snake game.
Gameplay is quite limited as these things go: the player directs Serpy ever
onward toward small, randomly appearing particles of what must be food or some
other snake-growth stimulant… upon consuming them Serpy extends in length,
eventually running the risk of colliding with his own obscenely elongated
coils. Barring surrounding walls, no other obstacles litter the playfield;
rather this game is one of endurance, seeing for how long the player can
neatly navigate the playfield before tripping up over his own snakeskin.
