Cool stuff! Pretty polished and complete-feeling! @april denise is right with their comment about being overwhelmed. I also didn't find it particularly clear when my tree cannon (the blue one...?) was refilled, and when too many flames came close to me then my heat level would tend to fly up to eight and send me back to my ship without much of an opportunity to apprehend the flames. I really enjoyed my time with the game, though, and I think  that with some minor UX tweaks you'll elevate this solid platformer.

Nice use of the assets as well!

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
