Unfortunately I am already sold out of the prototype carts. There will be an official cartridge run by Mega Cat/Video Game Sage in the next few weeks, so keep an eye out for that!

I've signed all the paperwork with Mega Cat for the release, so it's definitely happening. There's going to be a Kickstarter next year with a full-on professionally animated trailer. Getting all the marketing stuff for the trailer seems to be the thing we're all waiting to come together now. So stay tuned!
