Love the art style and character design. It took me a few tries to realize that I had to hold down the space bar because the “sound wave” animation is delayed. Consider having the sound wave expand out from the bird immediately and then contract the sound wave when space bar is released. That might make the press-and-hold mechanic more obvious.
Otherwise it seems like either the player or enemy hit box is too large because I took damage a few times without visually touching the enemy.
Thanks for checking out my game on stream. Really appreciate it!
