      • SPACE: dodge (tap to parry)

Q: Isn't it spelled "Rochambeau"?

A: Cosmic Rochambo bears no resemblance to your Earth-game.

Q: Why are we fighting?

A: Because you must.

Reverse Sale FAQ

Will I get keys for the other platforms for buying this?

Sadly, no. I wish I could offer cross platform keys for purchasing this, but due to the nature of business with the various platforms this is not feasible. You will, however, earn a warm and special place inside my heart.

Can I help out in any other way?

Absolutely! Reach out to me on Twitter (@seandick), record a video of you and your friends playing and post it somewhere (don't forget to link me to it!) Buy a copy for your friends, or even just tell them about how awesome it is.

This is way too expensive!

I'm really sorry you feel that way :( The game has been available for basically free for several years, and I've put quite a lot of time into it. If you're really hard up and just absolutely still want to play it, get in touch.

This isn't expensive enough!

Alright moneybags, show me what you got.
