Nice visuals and music! Good use of the theme, unfortunately I didn't seem to be able to raise or lower the bet amount. Either that or I was doing something wrong. In any case, well done!
If you have time please check out and rate my game as well!

The ability to change your stats with a "bet" is indicated by how many "bet points" you have in the top left. What I'm guessing is that you can make the first bet, but then not the second because you run out of points. You can gain more points by killing enemies. Still, it lets me press Shift and then Enter and makes me jump and does a bet with 0 points. In short, Shift is to start a bet, Backspace is to cancel, W is to raise points to bet (max indicated in the top left by 'Bet Points: #'), S is to lower, and Enter is to confirm.
