drawing, moving, and collision problems (pygame)

[nilamo]

For 1, each individual object (so players and enemies) should be tracking their own health (current and max). The only reason to have the player keep track of damage dealt, is if you want a counter on the pause menu or something to say "you've done 20383812 damage so far!". Otherwise, it's just extra info that isn't needed.

Also, a lot of the Player and Enemy classes look the same. They could maybe be the same class, renamed to just "Creature" or something. They both have health, they both deal damage, they both move, etc.
