The music to this game has some kind of fever dream quality to it.
I like the concept of trying to platform to reach a higher ledge, but I kind of find putting the mouse at the right position to be a wee bit frustrating.
Also, I know it doesn't sound like much, but it makes a world of difference to add some sound effects. The sound of a die hitting a casino chip, and a casino board, and whoosh when you kick the die into the air is all you need.
I would try and take this game a step further and ditch the casino setting and add some moving platforms, more obstacles, etc.
