So I got a bit stuck, and pretty fast :D It took me a while (actually read it in a comment here) to understand you can drag the animals, and once I started doing that, things started going pretty crazy - like, physics exploding all over the place crazy. I didn't manage to finish, but the concept itself seems solid. Perhaps the animals shouldn't spawn above your head when you 'summon' them, but at e.g. the cursor position? Perhaps you can only have one animal friend at a time? Something like that, maybe.
