Someone else mentioned the lack of tutorial too and I can't seem to reproduce it in any browser. Does this screen not show up when you start the first level? Anyways, thanks for playing even though this didn't come up, it can definitely be frustrating when games don't teach you how to play!

Sorry, I wasn't clear enough. I meant tutorial about monsters and the fact that when you run out of fuel your lighthouse goes out (I didn't notice that indicator in my first play) and also, that screen is shown, but it doesn't have text "Hold Right click to refill lantern" (I play browser version). And as I said these are minor things, because the overall atmosphere and gameplay give a lot of satisfaction.
