This game features 30 different levels. Since the user gets to set the difficulty of each level themselves, we decided to let the user play any level from the beginning, rather than locking some of them. 

As a team we knew that we wanted the game to showcase a variety of intuitive single-touch gestures. I took the lead on thinking about, and visualizing, a variety of ideas. I focused on how a broad variety mechanics would pair with different animal behaviors. 

This is one of many iterations of the flow I created for this game. The flow helps uncover questions for me to bring to the team. It's also a guide for the developers. 

I focused on simple choices and touch-friendly UI. There were many options that could be presented for customization, but after user-testing a customization prototype we decided that fewer, more impactful choices, were best.
