Pretty fun game. I especially like the level transition to the lightning section that was def an "ooooooh moment" and totally caught me by surprise (but more on that later).
At the start I wasn't to sure about the controls, however once I got used to them I actually really liked the way it felt. The punch at first felt meh until I really grasped how to use it. As you can tell I started to really like it, and then when I found out I could knock boulders into birds or trick birds into crashing into the boulders I was really all in. I love that you added the interaction between the hazards, I think it added a ton to experience and elevated it. I know it might seem kind of silly but many jam games would not have included that and would have just let the hazards overlap.
Now for the lightning phase. As far as scene changes go, it was awesome. It ran a bit dark and that made readability suffer a bit (could also just be my screen). However, it did add some cool new challenges because it forced me to stay close to the mountains, and it upped the atmosphere.
Overall, job well done
