Fourth'd. For 20 seconds of grey flash I at least expected some sort of message. Suicide, Despair, Blood on walls and a guy with horns. Big whoop. Contemplating suicide because of a maths test is justifiable for following it through, if you're retarded enough to do it in the first place then how are you going to function later in life? Suicide is just natural selection at work. People commit suicide for a number of reasons, crushing debt, homelessness, death of a life partner. Some of these cannot be avoided, but you know how to get through a test? Revise. It's very simple. If it's still too hard then just drop the subject and not your pulse. There, you wanted to me to think about it and I did. Sorry for sounding cold and bitter and apologies to anyone i've offended.
On a lighter note, they used Half-Life sounds to make it, maybe they saw the ending to Half-Life 2 and were inspired to make something depressing.
