Thank you so much! It's better to hear the sounds while playing, the medkits pickup can be checked by the sound. I didn't made the feedback like animation or effect because I had no time. The NPC should be stopped walking while the player healing it, or maybe that's just a bug because I've already played numerous times and didn't find that. I was using blender for the models, It was quite easy to use and I love the new version. Anyway thanks again!
