Roguelike Music Trainer

A roguelike game for training your brain to quickly calculate intervals between musical notes. This experience is targeted at musicians who need to quickly calculate "A + 3 half-steps" or "E - 8 half-steps". Answer enough questions correctly before time expires to advance from one level to the next. At the start of each level, pick a new "problem space" to add into the mix. Failure to complete a level results in a game over and starting back over at the first level with a single problem space. This is the roguelike nature of this game.
