Cool casual mobile-ish game. I liked the mechanic that allows you to swap only two neighboring birbs. I liked that it shows two birbs so you can plan ahead, but it works only on slower speeds: after a while, it shows just one birb.
The controls are a bit buggy (the birbs keep switching if you hold the mouse button and place your cursor kinda between two birb locations) but other than that I had no hiccups. The game feels fairly polished but maybe some effects when you match the birbs would add a bit of juice.
Nice minimalistic appearance, and I liked the cheerful kinda comedic tone the sounds went for.
Great job!
