I've played it again to see what's going on. My constructive criticism here, i'm really trying to help:
You really need to zone in on the sound your next jam. I think it's like 50% of the feeling of the game.
The biggest issue here is that the background music was so loud, that none of other sounds came through. I'd set background to 0.2.
I've heard the shooting sounds, but barely, had to really concentrate on it. Other sounds or interactions i didn't hear at all. menu popping up, touching item. EVERYTHING needs a sound. opening, closing, turning. It takes a ridiculous amount of time to setup and to find right sounds, but when you do, it will make the game twice as good imho.
