It's nice! You should deifnitely change the difficulty category. This isn't Easy, this is.. well, Normal to Hard, I'd say.
Also,
the control room is to the east, not to the west. You know, when the guy with the red key tells you?
And there are some minor grammar problems here and there, like someone referring to Juni as a "guy".
So how am I supposed to pass the room with the red key? :huh:
edit:
OK, I found it. I just wonder why way to the control room should be hidden like this
