Very nice Game, I think it's a bit too zoomed out and the font is hard to read if there is no solid background. Pretty nifty and smart idea, reminded me a bit of FTL: Faster than Light. Which as good thing ;)
I ecountered some bugs. One time the alien wouldn't leave the room and I just needed to wait for the timer to run out. One time he was just walking in the upper floors and then suddendly I got the message that he escaped. Other than that pretty nice game :)
