Designing the Enemy

I am going to describe what the enemy's are going to look like. Basically they are going to be square blocks that change colour. I am going to use bright colours like Blue, Pink, Yellow, Green, Red and a lighter Blue so that the colours are able to blend properly. I have now designed the enemy's and I am now going to upload them onto this post. I have just tried to upload the picture but it came up with error so I will do it next time I am on this.
