Interesting experience - to have a boxing round with kangaroo! But at the same time this is supposed to be a hentai themed game this kangaroo is going to be hot looking unshaved yet still you will have to get into the ring with her. Ofcourse since you are the boy and she is the chick the fighting is not an apporpriate thought so there will be another kind of rivalry - your health against her stamina! That is correct - attempt to obstruct all of the strikes that she is going to be sending into your face and when her stamina will expire sooner than your health then you will get a very special decoration from her... but for that you will have to demonstrate really excellent reflexes and coordination because she will be using her tail for strikes too! And don't be surprised if this game could make one to sweat for real!
