I like the art style and overall atmosphere/setting! The concept for the theme itself is really unique too.
However, the temperature switching is kind of finnicky, with noticeable delay for getting colder. I also found myself always just setting it to the highest temperature, which although resulting in me being detected by the guards very easily also meant that I could just outrun them.
I like the idea of using shooting as movement, but I also found it tiring to have to spam the mouse button to travel around. I think the big arrow might be bugged too - I rarely got it to work.
I really like the art style! I also think the concept works really well with the limitation. That being said, I found the jump part a bit hard to control, as it was quite floaty and I had a hard time telling when my character would fall. I'd also recommend giving the player a bit of buffer time before landing where they can input a jump, so that the player won't feel like their jump inputs were being eaten.
