Update time!
I think the original scope is not all going to make it in, so trying to polish up what I have right now.
So I went with my idea to not 'change' the laser color via a button, but have A S D fire each colour which works ok, but does lose a little in the theme of 'Change'
Its quite fun and challenging quickly getting the right button and hopefully as the waves speed up, it will be get very tricky.
Have player health in which I'll probably make a bar and a multiplier for now. I'm not very good with GUI so I'll have to take inspiration from somewhere.
Added in a basic background and starting to create graphics for the enemies. Over using the 'sin()' function for the spinning red enemy that spins AND moves using Sin :D
Anyways, will continue polishing and see what I can get done over the next few days!
