Trapped 2

Trapped 2 is a Snake / Nibbles clone with a tremendous amount of options. The object of course is to drive your constantly elongating snake around the map, avoiding crashing into yourself or the other players. It allows up to 4 simultaneous players on a single keyboard, which is pretty neat if it actually works. (Four people slamming keys at the same time may not be properly detected on most keyboards/systems ...) You can also play against computer opponents. The main problem is that, despite some gameplay powerups and such to collect, the game itself is a bit slow and underwhelming.
