I like the really cute, simple art style! It reminds me a lot of Rabbit & Steel - but with its own personality, of course. The music is pleasant, and the writing does what it needs to set the stage.
As for the gameplay, Plants vs Zombies is quite a fun inspiration. It plays well at a glance, and seems very fair and challenging once I get into it. It's a fun concept and excellent presentation overall, so I enjoyed it!
