You don’t need a clock to tell the time
Let’s suppose your player has three minutes to solve the current level. How do you tell her how much time she has left? Oh, I know, we’ll put a nice digital clock on screen. No? How about an analogue one, then.
Still no, I’m afraid. The nicest solution I have seen is in Wik and the Fable of Souls. Instead of a clock, the game has a creature that walks from the left side of the screen to the right side. If it reaches the right side, you were too slow: try again. You can even drop honey in front of the creature to slow him down; the equivalent of a time bonus.
The reason I like this approach so much, is that it is completely integrated into the game. How would you do the same thing with the player’s health bar? Or with the number of lives he has left?
