Backgrounds from the Pico-8 Community
This cart is less about the game and more about the people that contributed to it. It's tribute game in more ways than one.
First off, it's a tribute to Space Invaders Extreme that originally appeared on the Nintendo DS. It was Space Invaders kicked up a notch with a total sensory overload.
Second, it's a tribute and thank you to all the great little carts coming out of the Pico-8 forum. In particular, Invader Overload uses several of the carts from the TweetJam thread as manic backgrounds. Designs from zep, NuSan, kometbomb and others are included and create one hell of a show.
There were so many cool little demos coming out of the TweetJam thread that I just needed to find a way to use them. I consider Invader Overload a sort of TweetJam jukebox and hopefully we can all expand on it because you can totally add your own background! There's plenty of room left on the cart so give it a try.
This cart also features some great music from Brian Follick, aka, @gnarcade_vgm. He made a great music track specifically for this game along with a few sound effects, and without that collaboration, this game would have fallen completely flat.
