Very creative take on the basic flappy bird formula, it felt very engaging having to figure out your path as well as your height as you go. The art was also solid. Nice work!
I did get killed by a random (hornet?) that flew through one of the barriers which wasn't very fun because I didn't see it coming. Also it was a bit hard to guage the height needed to enter the barriers sometimes (which would probably need an indicator if you're about to fly into it or not on the barrier), as well as the position of things like the frogs jumping (maybe just a shadow underneath them would have helped).
