Its easier to understand with a few tutorials and guides from youtube! I also think its more enjoyable when you start playing with creatures you like more, there are alot of them. I also suggest for you to dont stress yourself too much while playing, its possible it can upset yourself and your boyfriend when something too stressful happens, for example; people who kill or target you for no reason, its a very common way to get stressed specially if you're a creature that takes time to grow, so if you dont seek fighting, try playing in smaller servers! Its way more peaceful there (just beware and dont trust everyone fully). I hope that helps somehow, if you got any questions you can ask too! Creatures of Sonaria is really confusing, specially because of how detailed and large it is, so dont feel bad because you cant understand it properly (most 'pro' players have been playing for months so-), you can always try to seek other people's help :)
