This entry shows a great concept, but I honestly think it's not really well executed.
Waiting for the input to register then update the image is entertaining at first, but it quickly become long, especially if like me, you missed some intersection in the path. You can also do several movement before updating the image, and that way you can avoid some scares entirely. You also can't rotate in this game, I think you did it by design but the environment feels like it should be explore with a 360 degrees view and not just stuck in one angle, the only moment where this work is during the long "BEHIND" corridor, but it mostly just impede the field of view.
So, in my opinion, you should be able to rotate and the image should update itself after each movement, and the whole process should be quicker.
I commend you for releasing an original entry, but in the end I didn't have much fun with the game, even if I really tried to.
