The concept is perfect ! The game fits perfectly with the theme, what makes your choice so clever it that this time you have to use the out of control in a "positive" way. Watching how the fire move linked to the geometrical use of matches you have used is fascinating ! I have loved to try different strategies and geometrical forms. Your game has a lot of potential. The 3rd level was for me much more easy than the 2nd one since the second level forced me to be very analytical and I have reproduced my technique in the 3rd level and it worked very easily. This game definitely need more polishing and new levels, it's so far one of my favorite game of this jam, great work ! I hope you will continue this game with more complex levels and maybe other mechanics like a square with water...
A picture to show you how.... frustrating it could be sometimes to be out of control ;) Congratulation for your great concept.
