The graphics, the UI and the sound design feal really well polished. However the gameplay is lacking some twist: The monsters are almost all identical, you just round them up and hit until you have enough eggs to level up, then repeat. The ghosts were pretty fun, since they are much faster and a little bit of challenge. The bombs could have added some fun if they were not useless (they take forever to explode, and do almost the same damage as a basic shot).
