This was a real treat. An interesting snippet of story, great graphics on top of a VERY cool pseudo-3D game engine. And I thought it very good how you thought of a contained, but variable style of play. With the character riding a horse, he doesn't have to perform complex movements or different actions (although it was great how he scaled the backs of the different creatures he rode)... but the containment of abilities didn't detract from the game at all. Well done.
The only thing I thought odd or out of place was the cuts to the story texts... the quality of them was really poor compared to the game itself. They were just blocky black text on a white background, and just seemed light-years behind the game itself. But otherwise, awesome.
