When I saw the video preview, I was instantly reminded of angry birds. However, it's the vertical version and it's the skeleton that needs to go through the hoops.
I played Angry Birds way back then and this game excites me since it's been so long now there's this version and another concept. My mind is blown away.
I noticed that it's rated 3+ but I don't think the graphics and the thought of the game are appropriate for kids since it's too dark and somehow violent. In some ways, it might affect their mentality.
I just think the app should be related to skeletons since this might cause some disturbance in children's behavior since there's a skeleton and hell. Adult supervision is strictly advised.
