Well a map editor in a game jam :O thats really impressive ! The first think i loved is the main menu it looks slick really cool :D The artwork is beatiful too :]
Now lets addres the elephant in the room there are no sound effects :/ which makes the game unresponsive. I would like to hear burn sound when burning grass :D Also the game is too easy you can even complete the first 8 levels just by random clicking :p
Other than these it would be cool if you decide to port it to mobile i can see myself making maps in my phone :D Loved it great work !
