SHIRK kuffer in games Please answer this

I made a mistake by playing a video game long ago named 'The You testament' which has so many shirk elements like magic soccery and like mediation to gain power and and perform soccery and story of Jesus according to Christianity and i didn't give any attention to it i just played for fun and i didn't take seriously and unintentionally without realising that it is sin. Now i realised it was completely Prohibited. So my question is did i commited shirk as i didn't know then,(now Alhamdulillah I'm a practicing muslim) and i was recently watching video games in Islam i then realised it. Please answer me as i didn't know it was shirk or kuffer .Please it's important I'm worried.
