The main character in Don's Dugout is a mole instead of a person because, well, it's more natural for moles to dig. But I had to antropomorphize him by letting him wear pants. Otherwise the players might have identified with the pigs instead. (No offense.)
I added the deadly obstacles more as a decoration than to improve the gameplay.
Some might wonder why the objects and tunnels look so randomly thrown together. That's because they are randomly thrown together. The reason they appear in identical positions each time you run the game is that I use a home-made deterministic pseudo-random number generator along with the standard one. But the clouds, the ground layers and the critter movements are based on "real" random numbers, so they will be different.
