From the start I didn't really understand what I was supposed to do, it was only when I had finished the first level I realised the acronym which made a lot of sense. The controls shouldn't be this way though, I believe you should change it to a default interact button such as enter as you are using the arrow keys.
Other than that the voice acting while good, the accents need a small bit of work and I think maybe you should have stuck to your original accent as this would have made the acting a small bit more convincing and immersive.
Overall, I think this is a good game and with some great map design and control improvements it could be a great game :)
