A really robust and complete experience. I initially felt terrible for losing 2/3 eggs early on, but after slaughtering 100s of lizards for an hour I got over it. The scaling terrain adds an amusing maintenance element to the gameplay loop, well done.
The squirrel vicars-gun of 100 acorns per second kind of blends the audio into a satisfying heavy rain on a windshield sort of noise, which is probably similar to what it'd actually sound like.
