This is an interesting game that I was unfamiliar with but a few people had requested it. The ability to look around freely does let you take in a bit more of the environment but some of the graphics do not agree with looking up and down. There is also a version that only moves the camera's x-axis which was requested by a user on Twitter. The hack works with both the original Japanese version as well as the v1.02 English translation hack.
