Contact data is still to be made available for this page. I won't give out Nino's E-mail adress in order to protect him from unwanted spam that might be ahead, if some sort of idiots got hold of it.
Nonetheless, if you want to contact Nino, the programmer of Gamebiz and GameBiz 2, then just simply visit the forum of GameBiz 2, his own page at Veloci Games or the homepage of Osiris Games. You will find ways to contact him there if needed. Reports about bugs within the game should be posted within the forum.
