Quality game! The core gameplay loop is fun, apart from a few glitches, such as villagers walking on air off the platform, the game is flawless. The fire spread seems realistic and chaotic enough to be fun.
If you wanted to continue to build, having levels progress from one to the next rather then saying "game over" could be nice. Some additional display by levels completed such as the percentage destroyed would work too. Some way to speed up time when fires are burning could be nice too. There's a lot of space for extra levels, I can't wait to see what you do!
Good luck on your future game dev!
