Nice game! I'm a big fan of the glow and particle effects everywhere. It makes the game look really mysterious. The flying tree ship was cool too - a neat use of the assets!
At some points, I got really mobbed by the fire and found it difficult to recover. I kept putting trees down to help, but I soon ran out of room because of all the burnt trees. :( Eventually I just ran away lol. I think having the burnt trees disappear or spawning less fire would have helped me out there.
Nice work overall. I enjoyed it! :D
