The Wonderland Board

I have a level where my pink cannon will not fire. This is the most important part of my level and I can't get it to work. Is there something that causes that to happen?

If the cannon is on a level BORDER, it sometimes fires for two tiles and then the fireball vanishes. Extend the level there and add a wall.

If the cannon is not on a border, you have too much fire on the level at once, overflowing the game engine. Remove some of that fire to fix the problem.

Thank you so much!
