Orton and the Princess is a rock-hard platformer with minimal graphics and a familiar objective. In each level you must jump "like a plumber" to navigate a fiendish series of platforms, spike traps and other obstacles, and rescue the princess.
The design is unforgiving. Orton moves quite quickly and thus it's maddeningly easy to overshoot a jump or overcorrect yourself mid-air and land on some killer spikes. For that, you are sent back to the beginning of the level.
But I could never stay mad at a game with such a jaunty soundtrack. And nor will you.
