Short answer:  Sadly, nope!  There are not going to be prizes. 

We were going to offer, however, we noticed that if we were to offer them, then we needed to restrict participation at the game jam event only to certain countries / regions.  In agreement with international regulations / laws.  We are sorting this out, so hopefully the next event we  have, we can be able to offer prizes and still be able to keep the participation as open as possible. 

We hope you do understand and if you decide to participate of the event anyways, well, thank you, we're humbled.  We do really appreciate your participation and we're glad you stay to share with us nevertheless.
