Very cute! Definitely got the vibe of becoming a larger predator with a matching appetite, as prey that was once closer to the player's size eventually can fit in the palm of their hand, and the once-larger prey are now 'unlocked'.
The dialogue is super cute as well, and encouraging in the sense that I wanted to play again to see if there was any cute lines I missed. Also, adding a little timer as a 'score' was another thing that made me want to try again!
