This is a cool take on the freeze theme, I could easily imagine this being a really nice game once fully fleshed out.
It's good that you get unlimited shots, this lets you experiment a bit and shoot everything to figure out what can be used in what way.
I have one big complaint though, and that's the aiming. I nearly gave up on the second level because I understood what I needed to do, the aiming was just jumping around so much that I could not execute on my idea... Maybe slow down how fast the angle changes or something? It is killing a bit of the enjoyment for me.
I would also suggest building the levels in a way that lets you understand them step by step. In the second level for example I only saw the mirror kinda thing pretty late and only then understood that it's part of the solution. In the third level I would suggest some color-coding to help the player understand which gears control which part of the level. I had some trouble understanding how the pieces of the room work together.
Overall a great idea, fits the theme, and an impressive amount of levels and gameplay!
