Pretty difficult but fun game.
The controls and the general feel of using the flame thrower to move trough the levels are good. The visuals are also nice, the levels could us a bit variety though.
I had a really hard time even reaching the second checkpoint. It would be great if the first level or sections would have been easier to get used to it.
What I really like is that you don't reset everything when the player dies. If ice was melted it stays melted. I also really love the little animation you added to the flame thrower when using it. Nice little detail.
Even though I could not beat the game I enjoyed playing it. Good job!
