Really cool angle with the theme!
I loved the Intro stuff, there was actually a bit of story. And the way the scans/levels were set-up, it really sets the kind of mood/tone I was expecting.
Unfortunately, I only managed to get to Scan #2. I don't know if it's because the Raycast detection or whatnot(not a programmer, sorry) just wasn't very responsive. It's unfortunate, since I think the game has pretty good game feel. It is lacking in feedback, like others have said. Since I don't think you're using a 'gun' even though the control is 'shoot' you could still have a lingering animation of like the defragmentation or whatnot, and it could even hit a few enemies(if they're clustered) that may add a bit of depth to the combat, but it may also break the current flow- so I dunno, haha.
I don't know if it was the game's intention, but I would click, hear the noise like I shot the thing and it would keep coming at me for a few more moments before it disappeared- this is mainly why I didn't make it past Scan 2.
But, again, I do love the art style and narrative. It's a cool game, and I hope to make it to the end someday!
