Nice little mini-game, I'm not sure if there's more but it kicked me out to the main menu after I danced. The bat costume I bought didn't seem to do anything so I'm guessing there was nothing I could buy and use.
I really didn't like the sound effect for the characters talking, and was fine playing the minigame but would be more intuitive with arrow keys instead of words for the directions.
It's a shame you didn't get much chance to work on it, I feel like this could have been a top contender from the segment you've posted.
