Loving this game. Going to play it again tonight. On my first playthrough, I'm not super sure if I hit a soft lock or the end of the current game content. I got the black wing first, and the second one I got what I think was a new beak gun and when I took it my beak went back to normal so I didn't have a gun and couldn't go through the glass door.
Love the theme, love the unique idea. The game feels really good. Jump and double jumping and the camera following you smoothly feels great. I was a little confused by how to do wasd + space + shift + use my mouse but I couldn't notice a difference when using dash, so I just didn't use that.
