This was a good entry. Responsive controls. Cute graphics, including the environments (which were simple but serviceable).
The mechanic of eating your enemies is very fun, and gives the player a reason not to avoid combat.
Although the music was pleasant, I would say it did not entirely convey the spirit of predation.
Also, I would recommend that the enemies react a little more when struck. Maybe jump back slightly, or at least freeze for a fraction of a second.
