The idea for the game is pretty original and I had fun.
There's a lack of distinction between what will kill you and will not. The sort of lava on the ground looks the same as the one above, and there seems to be giant red flames but you're fine going through them.
The music and sound effects are turned off by default for some odd reason. It's a shame because the music is really good and catchy!
I haven't found a way to get the jerrycan 2 and 3, so I can't comment if there's anything further than that.
Great work!
