I already have a failed career written (I was for another jam) but it's in french. Is it okay to submit it as is or do I have to translate it to english to participate?

Go ahead an submit!

By the way... There are some real nice folks on the ItO server who are fluent in French that would probably be happy to help make an English version....

it's submitted keep in mind it a joke submission from another joke jam but I really think it's playable.
