Design 3/5 : I don't like the black background with just the text, it is too simple IMO. The assets and music look good tho.
Theme 5/5 : 1 directional is a nice fit into the theme
Originality 4/5 : seen before (in mobile games) but still not enough for me to duck more stars.
The controls were not really intuitives... The game looks good with cute art and nice music. I'll still say that it lacks smth like a cool move / combo, the slide was nice but it need to be more useful. I don't get why you have to use the moves to earn coins, but you can turn this into smth like a "reality show" were your style earns you money (for exemple).
Good job!
