I'm sorry to hear that :( I guess that I should made some kind of an in-game tutorial in the future. In case you would like to give it a second try: wasd — controls, mouse roll — change active item, e — reading a book (could only be done if nearby light is on), LMB to use the active item, active items: torch — turns candles on, vodka — heals you (works only if you are injured), thurible — kills nearby bats and imps, chalk — draws a circle that makes you invisible to monsters.
