I found this level quite strange ...
I was unable to understand anything without all of your new hints. I think hints are useful, but thay haven't to be necessary. And because the level is too complicated, these aren't hints, but likely a to-do list.
There are much more possible reactions than these four ones, how are we supposed to guess the correct ones AND the correct order ? Is there a logic ?
By the way, with the background we can't see the ashes.
I also wanted to tell I wasn't able to freeze steam, and that the level was validated as soon as i put the correct elements in the containers. I didn't had to correct the wires.
