What a fun idea ! I had a very good time on your game. It was so funny and unusual to have to whip slaves to do a race. :') It's not so easy to play, because two whip on the left and your slaves go really really hard to the left ! You have worked to do to get it really playable (like the menu :p) but the race in itself is already good. Maybe add an action to speed up the slaves ? Because I had an "accident" with the second racer, and after that it was impossible to get the first.
Congratulations to your team, keep creating games !
