Right now the items you get from looting houses is a TV, a remote control, and a portable radio once you get all 3 you get a "Navigation" item for the mothership. I need to add little text popups explaining the mechanic. The game is missing a lot of tutorialising. I need to work on the UI some more, I want the console bar to pop up tutorial text when you first find things.
I like the idea of something that changes the appearance of the alien that could be funny, and some of the houses give you nothing right now. I suppose you could steal a bath robe or something and have it show on the alien sprite. Nice idea.
