Definitely a challenging game at first play and those dam alien scum kept overwhleming me! :p But I love the concept here - I'm not sure if I was increasing the power or not of the laser, maybe a more clear UI would help there, or labels on each "control" to remind what each is, but the tutorial screen definitely helped! I really like the idea of things happening outside the ship and you can still move inside - now if the shield could be a once off cool down that surrounds the whole ship that would be great just to give that extra time, because I was really getting into it :) Very fun idea, great job!
