This is a good game, but for some reason it bugs out with the steam from time to time.
For me right now, level 9 won't work as it is supposed to.
Heck, I even googled up an answer to check if it wasn't just me being stubborn, but no, I have placed everything correctly, but the steam won't travel upwards.
