So I gotta be honest, it took me awhile to figure this one out. I almost gave up on it, especially since restarting the first level re-triggered the tutorial, which took awhile each time to sit through and really didnt help me get it. After it did finally click, it was definitely an interesting puzzle game that I think was hindered by your fire spread mechanic, since that pretty much just makes the level impossible to complete and you need to restart, which can lead to more frustration if its a tutorial level. But all in all I think its a good foundation for a unique puzzle game with a great look. Good work!
