Arcy 2

Arcy 2 is a VGA puzzle game that might remind you a little of Kroz. You play a smiley face who must collect all of the keys in a level before you can leave. Each enemy moves in a specific way, so the puzzle is figuring out how to move through the level without getting killed. Some enemies will only move if you cross their path, some will kill you instantly, some move in straight lines and only turn left or right, and some will try to trap you.
