I've only compiled it for linux right now so you can try it if you are a linux user if not I'm afraid you'll have to wait until 1. I find a windows machine or 2. learn how to cross compile.
You will require all the usual SDL runtime libraries installed (SDL, SDL_image,SDL_ttf,SDL_mixer).
The game I think is similar to space invaders or at least that is the closest thing I can compare it to. It is by no means perfect for example enemies ignore each other and will happily shoot through eachother/move over and beneath one another and this is partly laziness and partly because I wanted to keep their movement and positions as random as possible.

You're welcome to criticise it but please bare in mind it was hastily cobbled together in one night. Oh and you'll notice there is a level counter, I was going to implement levels but decided not to and forgot to remove that.
