MORE PROGRESS - But not as much as I would have hoped for.
Day 2 is now over for me and the team and more code has been written, more art has been faffed about with, and some more backgrounds have been produced.
Today's adjustments:
New character has replaced the old one,
The character and zombies have decreased in size by 20%,
The art has been gone around again to remove any issues that were arising with animations popping back and forth with a blue line around the edge,
A bullet has been added that can kill zombies upon impact,
Body parts are now flung across the screen whilst roating around their center,
Those body parts now are added to the walk able ground in their specific rotation to allow for mounds to be created,
Added jumping and control for the character,
Allowed for the character to jump up through layers of body parts - to prevent them from getting stuck,
Added a new type of animation for the Zombie - this will be behind the fence in the main menu,
Added a new animation for the Zombie to climb over the fence - from the background to the foreground,
A lot of music has been listened to.
Things to do tomorrow:
Music and sound effects,
Main menu graphics and functionality,
Finalizing the game loop,
Publish the game to itch.io,
Finalize the Zombie climbing over fence animation in the drawing order,
Add a helicopter to save our hero.

Some good work done today by me, @renegadePunisher and two artists who are not on this website.
We have yet to have many ideas for the name of the game so any suggestions would be kindly accepted.
