The art style is great, I enjoyed the difference in how you rendered the player and enemies between cutscenes and gameplay. There's some lovely touches like the carrots for health, and the way the tomatoes jump every once in a while to throw off your shots.
I'd suggest making it escalate a little slower, as the screen ended up full of enemies very quickly with no real way for me to escape. Also, is there a way to restart the game without exiting on a game over?
