One obvious flaw
You shouldn't be able to eat the worms when your health is full. Either that or the worms should pop up over the time course of the level (you can still limit the amount so people don't wait for a worm). Otherwise, it is annoying and unnecessarily complicating and frustrating to use up all the worms in the beginning as you try to kill the first enemies. Overall, it was fun and I will be back to get better.
