Fun game!
It took me two playthroughs to really understand all mechanics - they are pretty well explained but maybe trying each one individually before the main level would work.
I feel like the special abilities could have more effect and be more expensive, as I didn't really notice much after buying them.
I really loved figuring out which fire to click at each point, I would also make clicks affect the fires a bit more so that the player will have more control.
Overall it's a good game with a really cool concept.
