This was honestly pretty fun - I kept trying more to see what other enemy variants there were. I was a little confused with the mushroom shield the plants had and thought something was broken because the crow kept dodging the wrong direction - but it was being deflected! A sound effect or visual bump would've helped in that regard.
I like your art style, super jealous! Did you make your own music? I like the crow effect you put in there, hah. The theme rocked. Good luck on this entry man, good stuff!
