The art and premise is really cool, did a good job on the how the tongue works.
I'm finding it really hard to beat, sometimes the hit box with the tongue seems a bit off, It's fire directly through a fly and not pick it up or it'll catch a fly that's off to the side of it's hitbox.
I think I figured out your unreliable narrator as the closest I got was the flapping of the wings and like half it's sprite on screen before I game over, can never get much further than that cause the meter is going down way faster than I can catch anything.
But from what I've seen, I like. the on screen prompts and how it matches up with what I assume the end is.
Nice work.
