As DK1 listed all the random stuff like how much gold you have made, etc,etc, after each level, how about we have a section on the menu that lists all achievements / stats?
like mass effect or spore, if you have played those
- number of slaps given
- number of earth tiles dug out
- number of creatures attracted
- hero's killed
- levels finished
- spells used
- imps died
- creatures sacrificed
- hidden objects found
- etc, etc
(note, this is not on a level to level basis - these stats are added and added for the life of the game)
we can even make it so that if have "attracted more than 500 creatures" (just an example), you unlock something, like video's, or game artwork, etc?
