Fun little game! I made a video of it for others to see!some ideas for you:
1) It took me some time to realize clicking on the fruit the animals ask for doesn't give it to them, it just drops it on the ground. I had to drag the fruit to the animal. Pretty obvious in hindsight I suppose, especially when 2 animals appeared but my first reaction was to click the correct fruit, not drag. Maybe a message telling people what's going on (like a backstory too - why are these adorable critters coming to me anyway?)
2) an achievements system would work really well with this game, or a competitive element like fastest animal served, or stats on how many of each animal served?
