Bots 'n Bolts

Fixed graphical bugs (like trying to place buttons past the edge of the screen) on some devices.
Fixed missing sound effects on some devices.
Sometimes it was hard to find power-ups, and it was unclear that the power-ups were necessary to reach the later levels. Now the game guides the player so that it's easier to find the power-ups (but players can still disable automatic level selection if they prefer to explore without this guidance).
