We appreciate your comments and will keep them in consideration!
We actually received the same complaint about controls a handful of times from others during playtesting! Many felt a bit complexed by the idea that there was no freedom to look up and down. We did experiment with a bit more freedom to look around, but in the end felt it altered the experience too much from our intended effect. However, we will be noting this, and if we ever choose to develop a similar system in the future will be trying to alter these to feel a bit more natural!
