Cute game! It took me a few minutes to get my bearings, but I was able to figure out the objective and systems without any extra instruction, which is great. I also really like that you included a re-try button so that I don't have to wait for the time to expire to try again if I screw up a level.
Some feedback:
- Movement felt a bit too slippery for a bird. I could understand the movement being slippery while "full", but when I'm not full, I'd expect to be able to slow down or stop much faster while on the ground.
- It wasn't very clear that the platforms were "off" without the gear being engaged. I definately wasted a minute or two falling through the platforms on the first level wondering if I was just too slippery, or if it was a bug.
- It wasn't clear at the start that the egg/nest was a button and needed to be landed-on. An arrow pointing down to it on the first level (until you press it) might have helped, or making it look more like a button, but I honestly like that it looks like an egg in a nest.
Overall you did a great job with this, and you should be proud!
