Thank you for the kind words!
Mouse navigation is definitely a thing we wanted to do but didn't budget enough time for. So we went with a WASD scheme which was easier. We will consider the placement of the map/radar as well - not a lot of thought went into that yet :)
We're glad to hear that you enjoyed the objectives and the ending (perhaps endings? if you have found them). Hopefully we can deliver a full experience at some point in the future.
Cheers!
