So here's the basic idea: Vampire is "sailing" across the desert at night, under the power of his thralls. And obviously he wants to get to his destination before daylight. So he needs to feed his thralls candy at specific intervals to keep them motivated. Also, they are fickle, and their preferred candy changes over time.
This is a rhythm mini-game with a symbol matching element. You need to time your candy feeding to the beat, but also make sure the candy matches what they want. Get it right, and you speed up. Get it wrong, and you slow down.
I've never worked within this genre before, so it should be interesting.
