Weirdly fun, especially when you have multiple creatures on screen. If you wanted to tap more into the humor side I think some sort of text to speech implementation could make this game absolutely hilarious when you create a lot of creatures.
As for making it a legitimate game I would say to focus more on the virtual pet mechanics and allow the player to customize each creature and let the creatures pick up more phrases based on the conversations they have. Lots of room for expansion, you've created a very open concept and I really hope you continue development because I would love to see where this goes.
Very unique concept for this jam, this one definitely sticks out amongst the crowd in its own way!
