I'm really picking the low-hanging fruit here, but I love the cleverness of the overall design. Each game is a cliché? That's the cat's pajamas. And I appreciate the level of detail - everything from how the music sped up as the timer was going down, to the very cliché Wilhlem Scream when the doctor takes a dive.
I did have a similar problem to some of the other reviews with using WASD instead of arrows on a few things. But once I figured that out, it was off to the races.
Great job all! Very fun game, one of the best here.
