BIG PROBLEM. You display the controls for movement, and then take too long to display the controls for combat. I tried all the movement keys, and as I walked through the door I interrupted more exposition. Lock the door until the tutorial ends on the first playthough, or make some sort of "skip tutorial" button so players know to stick around.
This has left me with a bad first impression of the game, and I'm sure it has done for others as well. You could have much higher scores if this was addressed, and then re-uploaded.
