I like the theme interpretation, and i'm glad to find a game that has actually more than 1 level ^^
I played it for like 10min and only found 1 bug (sometimes the fire didnt remove but the machine was fixed).
Last thing, the art is great but you should remove the compression, because it is pixel art. what you did with the player and the smoke pixelart you should do it to every single sprite if its pixel art ^^
