So, I added other characters to the game.

Badgers and Snake.

You know, to go with the mushroom.

And naturally other characters lead to COMBAT.

But combat is complex, and it is easier to implement running from combat.

So now you can both engage a snake or badger in combat, and run away from it!

Brave Yer! Running from snakes! Like Indiana Jones.

Or Raul from UHF, who don't need no stinking badgers!

Then, to make the triangle complete, there's that one scene in UHF where Al is spoofing the boulder scene from Raider of the Lost Ark.

Yes. 

Movie nerdery!
