Quite a nice little runner, with a good twist that fits the theme. The scrolling was very stuttery for me. I played in browser in Firefox. I really liked how the music transitions seemingly synched with the environment transitions. Good work!

This turned out nice! The controls changing was difficult, but it was fun playing through the different environments. Very pretty game with a really nice atmosphere. Good job!

Love this beautiful art!

It's so stylish and beautiful! I loved so epic music and those parallax backgrounds. I really enjoyed this game :)

In addition, it would be better if the birds did not appear when control changes occurs. I was just dying from pressing the wrong key. However, this did not stop me from enjoying the game.

This game makes me go YES! Reminds me on Google Chrome offline game with better art!

I liked the art a lot! Reminds me of the Google Chrome dinosaur game. I wish the switching mechanic had a little more to it, though. Nice work!

nice art but it's just a t-rex game with swutching controls.. 

Nice game and amazing art :)

cool game, I just wish there were more enemy types :]

Visuals and sounds are great. However, there are some gameplay problems:

1. I can jump while crouching. It makes the game incredibly easy and destroys all the challenge.
2. It's hard to see birds, especially, during the night.

It's beautiful, but really boring to play :

While jumping requires waiting the bird to get right next to you, bending down doesn't have any disadvantage and quickly becomes the default action. This really underlies the main challenge of the control switch as it allows you to always keep track of what the right action is.

Also, be cautious with simple random events : I got a high bird six times in a row; lack of variation is the last thing you want from that kind of game.

On a good note, the backgrounds gives a great vibe.

Art looks great and the game works well. Sometimes the birds were a little hard to see. Good job overall!

Really good mood with both beatiful art and music. There are cases where seeing the birds is a bit hard like said below.

I feel like the gameplay is really too simple, reversing controls surprised me the first time but got used to it after that, a better fit to the theme would be found i think.

The low flying birds were quite rare, so i spent almost the whole game holding crouch, only switching key when the background changed which made the game even easier xD

For some reason the parallax was really not fluid, fullscreen or not doesn't seem to affect it nor restarting the browser.

Also sometimes you would get birds going at different speeds at the same time, which can make certain jumps impossible.

Cute game, some more explanation on why you run would be nice

Beautiful art and well executed. I agree with  WhiteNull on the merging of birds. On my Laptop it lagged a bit. But still very playable.

What a beautiful game! The simple mechanics work, since I find it really hard to jump when I press "down". Really well done.

However... I need more information on that lore. What am I running from or to? Why am I running day and night? Why are the birds so damn angry at me? What happened?!

Art and music are amazing. birds sometimes merge with their surroundings making them difficult to see. I would diversify the types of hurdles. Separately, I want to note that I liked the dude's pose when he sits, he curls up in a ball :D

Nice art, its difficult to handle the reverse controls at first but its rewarding to pass those dang birds.

I made a similar game, but without the flip controls (or crouch) nice touch on that.

Lovely art and use of music! The gameplay works quite well, and getting caught up on the controls got me at least five times. Nice work!
