I love the idea behind this game! The navigation through the map while also watching out for the monster is a very cool concept. Visually the game looks very nice, I'm a fan of the style!
However, the game seems to be in a rough state at the moment. First of all, the dialogue should have the option to be skipped. It was very annoying to have to wait for it to finish in order to try again after dying. Second, the monster behavior is not very clear in my opinion. The guy on the radio says that you should keep the door open when it's behind it, but it killed me both when I listened to him and when I closed the door. There is mention of hiding from the monster, yet there's no apparent way to do it. Another good addition would have been a game over screen or a simple fade in and out, because I didn't even realize I have died until the dialogue started repeating again.
You have a great concept, and I would love to play it again after some improvement!
