Good game but it seems like it needs a huge graphics upgrade. It's hard to tell the zombies apart from all the other eggs. What I thought were trees looked like slime puddles until I moved the camera. One of the eggs had trouble getting up on the roof at one point. He kept jumping and jumping but humpty dumpty couldn't get up the wall. But beyond that it looks like it could become much bigger/better.
Yea this is definitely a WIP. I'm going to change how the game works quite a bit. Rather than blocks filling in from the back, the board will be a cube and blocks will come in from the center of the cube and spread outwards.
Make it so you can press the space bar to restart rather than...
Lifting your hand up, moving it to the mouse, clicking the button, moving it back to your keyboard, rinse and repeat.
Nice and simple! I liked the camera twists you put in there. My only suggestion for now is to change the checkpoints to something that doesn't look like a poisonous puddle. I jumped over the first few on level 1 because I didn't know what they were.
Good luck with the highscore. I made a little program in Blitz3D to move the mouse across the screen where the game window was. That was fun :) Just ignore my score if you want lol.
 "Zombie Invasion of Eggland"){kind=icon}
