Grid Shooter (Total Progress: 5%)

Hi,
I have embarked on a 2nd project which for the moment I will call "Grid Shooter". Basically, up to 50 waves of enemies will come and try to get to the end of the path (where the village is). If an enemy gets into the village then you will lose one of your 10 lives. You have to buy guns and turrets to try and kill three types of enemies:
1. Ground
2. Air
3. Water
You will be able to get money by killing enemies. When a wave comes, and an enemy comses into the range of the gun, the gun will shoot. The enemy will have a certain amount of health. Waves will gradually introduce new tactics and get more difficult.

I have done the grid engine and now I am working on debugging that and the AI.
This is the first ever screenshot of it:

If you would be interested in creating similar graphics to the turrets, please contact me for more details!

Thanks for reading!
