Thanks for reviewing! We are glad you enjoyed! Keep in mind this IS a demo and gamejam game, but we are working on the issues. Yeah the monster isn't supposed to be killable (yet!), you simply have to avoid him while trying to find an exit. Your guns CAN slow him down, but he won't die (though it might be possible to glitch him out of the backrooms), but that's the extent of the damage you can do to him. So there IS an ending which sets up the full version of the game!
As for the issues, we are working on a controls/tutorial screen of some sorts.
The voice acting may sadly be something we cannot fix as one of the voice actors has to send his lines over via discord due to a difference in where we are. I have tried to mix it properly, but I don't know if I can do much better without both of us using the same mic.
And yeah, the cameras were done by using a modified level file with me simply screen recording moving my mouse to simulate a camera. This was one of the last things we did and weren't 100% sure if we wanted it to seem like the player was looking through a security camera or if it was a "cinematic" camera they were looking through, but in the end it was meant to be a security camera to fit with the Commanders quotes (the voice at the start isn't the player, it's actually an unseen commander, the player, at least in the demo, is silent).
