Akrasia ("acting against one's better judgment" in Greek) is a visually beautiful game with pleasant music in which you, a rotund character manipulated by arrow keys or WASD maneuver about a maze.
In the maze are "pills". Eating a pill increases your score, but reduces your life. At various points along the life bar, which is in the shape of at tree branch, are icons representing a house, a pet, people (family or friends?) and a heart (love, presumably). As your lifebar decreases, these icons fall away.
Periodically, the maze turns dark and nasty, and monster chase you. You can turn it happy and pretty again by taking more drugs, I mean, intersecting another pill icon.
An arrow near you points toward the exit (which moves around), and you can chase it until you find it, and then use it; what you get on the other side is an end-game screen which varies depending on your activity in the game.
Ostensibly, this is a metaphor for addiction, or something, but I note that your life restores when you go into the "ugly" maze, so the way to mazimize your score is to take lots of drugs, but not to the point that you lose any of your icons, restore in the ugly maze, avoid monsters, and repeat. So one could argue that the subtext is less "addiction is bad" than "taking drugs is good, so long as you avoid going overboard." Or something.
It's kind of fun, although I'm not at all sure that the metaphor bears the weight it's being asked to hold.
