Pressing the go button more than once resets the spin animation but preserves the result
A complex metaphor about fate or something
For a moment, I was thinking that this was a troll-game that always made you lose, in which case I would have probably rated it 4 stars for being clever and artistic, especially with the name "Lucky Spin." But then I realized that it's not a troll game, it's just actually lame.
If you win you should allow the player to keep playing until they are bankrupt. I like the visuals ^_^ Would be nice to have some sound fx and music.
