This is a really nice concept. The sound effects are nice, the music is decent. I played until level 10 so I don't think I got into the meat of your game. It took me until level 10 to understand the difference between the 2 forcefields but since you didn't need to explain them this is perfect. The one thing I struggled with was figuring out the "additional feature" in level 8? It took me a while, since you're interrupting the game to say something anyways, I think you might as well explain more on 'what' you actually updated.
Overall after these 10 levels I was starting to get bored a little. I didn't see a reason why I had to keep going, the game could use a little story or drive to keep you moving. If that happens later, then I'm sorry for being mean ;)
I really love the mechanics of this game and think it has great (steam?) potential if you can spend some more time polishing it and adding a reason to play. The game's mood and how all the assets come together can also be improved a little I think, maybe some particle effects? The walls around me felt a little too omnipresent and suffocating. While the sci-fi theme works nicely and quickly provides the link to portal games, I think you could brainstorm a little on what else this could be? You could be a young witch in the woods trying to succeed your midterm exam, racing against the clock. The woods could provide an easy barrier with brambles or trees and maybe some witchy spectators? Or a magic beetle in an underground tunnel system trying to find food or just a man trying to reach the house of his crazy inlaws with all their home security to ask their gay son for his hand in marriage with suburban vibes.
The possibilities with this game are endless and I think it could be a very fun new puzzle game
