Throwing with your tail is super weird and creative, I like it. It took me a while to realize that the stone velocity relates to damage. Realizing this mechanic and then hitting birds with high-speed throws was pretty satisfying (I one-shot the falcon boss by accident because of this lol).
Like others have mentioned, the controls feel a little slippery and hard-to-use, but the throwing mechanic is pretty cool. Also the owl boss did some strange things on my screen; It would periodically lag the game during its teleport attack, which seemed tough to avoid due to the lag.
The sillhouettes are cool and landing throws is pretty satisfying. Nice!
