Impede

Impede (or IM-PEDE as it shows in-game) is a variant on the Snake / Nibbles type game. The main difference here is that your snake doesn't move automatically. Instead, you attempt to strategically maneuver through the Pac-Man-like maze, eating all of the dots. As you eat, your tail grows. So you need to carefully plan ahead, or you'll run out of room and crash into your own tail. It's a neat puzzle twist on the classic Snake game that looks easy but can be difficult. There's also a timer so you can't sit around thinking too long. The shareware version has 6 levels with different layouts.
