Tiny Arcade Space Invaders Super Impulse World's Smallest

Legit version of Space Invaders, responsive controls, sharp screen image--cool details too, for example the marquee lights up when you're playing. My only real misgiving with the product is the attached keychain bits, it's hard for me to imagine anyone wanting to subject their game to the hazards of being on a keychain, so it's really unnecessary and a bit of an obstacle unless you choose to remove it, and then of course you'd have the business of removing it to deal with. That's why I didn't give it 5 stars.
