It's a nice game and I like the concept, but I feel like it's a little bit hard. I would move my character slightly out of line by accident and the whole group would just swarm me. It gets sort of annoying later on.
Also there was small bug in level 11 I think, where sometimes when I throw my plant at the big gnorm, another gnorm would throw a plant at the same one and pick up the sweet sap thing at the same time. It doesn't really affect the gameplay that much but it did confuse me when I was playing.
Yeah that's about it. I like how it looks though.
