Will Conine is probably a young author; at the very least he is an inexperienced one. The Hangover has all the marks of a first game attempted with enthusiasm but little knowledge of how a good game is crafted, including a lack of synonyms, guess-the-verb problems and room descriptions that don't change with the state of the world.
Exacerbating these problems is the prose, of which this is a typical sample:
"You have a horrid hangover and no asprin in the apartment. This is your bedroom. Your ill-loking bed takes up most of the space. You have a closet and a bath robe on the floor. you should really take your robe and put it on. Its a good place to store things. To the east is your bathroom and to your west is the rest of your apartment."
According to other reviews the game is not finishable due to a bug; I can't speak for that myself since I never came that far.
We can safely conclude that the author should not have entered this game in the IF Comp, where it naturally generated harsh criticism. More constructive criticism could have been gotten outside of competitions.
