I didn't read the controls before starting the game. Walking up to a door and pressing E expecting to open it and just kicking it off its hinges was quite an intro.
Looks nice, but I don't know if there's much else to say at this point. Shame there's no enemies you can try out the guns on.
I hope you're planning to add reload animations.
Movement feels nice and responsive, though the area for testing is quite limited.
Only problem I noticed is that the slide sprite stays up a little too long if you merely tap it, letting you do silly things.
