This is quite similar to what I made, both challenging 2d pixel platformers with heavy emphasis being placed on a specific unique mechanic, in your case it being the limited flight. We even both put a "your time" at the end! I got 339 seconds.
Speaking of the limited flight, I've always thought that games where the player is a bird should allow the player to fly but find a way to balance it. In your case you did that well with an energy meter.
I really enjoyed playing it, it's got that atmosphere element that I only partially achieved. The graphics and audio are very nice and you hit the other categories for 4 stars from me. I would have put 5 in game design but I reached the end having only lit 3 campfires. I saw the fourth but assumed the path I was going was going to take me back to the fourth guy. Instead it just took me to the endscreen and I won.
I really want this to reach 20 votes so that it can place since you need 20, I've already voted yousr so I can't do it again but I encourage you to play some more games by other people since that encourages more people to vote your own game. I'm also encouraging a few others in the Brackeys discord.
