Flipping Finches was a game I made for Ludum Dare 53 back at the start of May.
The theme was Delivery, and I got 9th in Theme! It's a difficult-ish flying platformer where the bird will do a flip every time you turn around.

I originally was not planning on doing this game jam this time around, but the concept of delivery has been on my mind for a long time (ie Courier Canopy), and I've been slowly exploring possible mechanics with birds (Relay PeaJay, this game). I don't plan on expanding the jam game but there were some interesting experiments between move sets and player input I will still have to figure out.
