Finally, a game that works out of the box! It respects my time, and I appreciate such craftsmanship in today's age of "just IKEA it bro trust me".
The concept is sound. You control John Spacebo, defending your spacehut against evil space gyrocopters, firing their own munitions back! Ha!
I must deduct points for the lack of chaos. There should be more spacecopters.
I like that you can still keep playing after you lose :)
