Honestly not a bad endless runner, if a little basic, I do like how you have more shape variety then just "Square, Circle, Triangle" and the power ups are nice, but according to the game page there's a chance it will do nothing, I don't know why a power up doing nothing is a thing in this game, what's up with that? The art is nice and I like how the main character's eyes glow when hit showing feedback from them and showing you put some polish in

One hand fair, on the other, I feel like you could have easily done something like this
Powerup():
If Health >= 3:
Health = 3
Elif Health != 3: (or) Health <= 2 (or even) Health == 2 or Health == 1:
Health = Health + 1
I don't know Unity's coding language so this may not work if you just copied and pasted it in but I feel like something like this would work out for you, and if that doesn't work I would suggest making it give points when the player is at full health.
