Well, I'm not at all sure where I'm going to go with this theme yet. Maybe a tower defence game, I haven't done on of those yet. Anyway, I'm tired so sleep is definitely in order before I decide on anything. Can't wait to get started tomorrow.
Here is the screen shot of the playing level so far. No characters or weapons or even any of the GUI except for the area being boxed off. It's a lot better than nothing I guess though.
The tile set I used for the Space Pirate Hideout was made by:

All the other graphics so far were made by me which is why they aren't so pretty but they get the job done.
My next steps through this week are to get the character sprites animations looking good and the AI working as well. I am going to make it so that the player makes their character's attack by clicking on them so there is no need for complex controls or anything like that.
