Hey all!  I wanted to try and "diary" out my work on this project, as I foresee it being a much longer work.  With the help of my brother, we've got four different style of bad guys out so far.

Centipede - walks around until in range of the player or damaged and then turns into spinning ball of death.

Slugs - slide along the wall and will shoot at the player based on their Y coordinates

Frog - Will spit out two bubbles when player enters their range

Bird - Flies along the top of the screen until close enough to the player, and then will swoop down and shoot three feathers, before flying back up and off the screen.

If you have any ideas, let me know!
