DooG updated to v0.91

DooG v0.91

Slowly but steadily progressing towards completing what I had planned for the 1.0 version of the game.
The game now has a melee attack enemy, watch out for the mighty slam!

New Stuff:

•  New enemy: Sea Chicken!
•  Switched up the weapon pickups in level 3
•  Spiced up a bit the credits roll
•  Enhanced a couple of secret word effects!

Bug fixes:

•  Fixed a bug with a missing Broccoli sprite
