When Exploding Kittens launched their Kitten Games sub-brand for ages 4+, I was lucky enough to work on this title as one of my earliest introductions to packaging design.

Below: One significant contribution to the entire Kitten Games line I am proud of is the Kitten Games spine. The CEO of Exploding Kittens wanted to add the story of how he and his daughter came up with these games. I suggested to use a side panel  and created the initial layout for all games to use. 
Below: One of my contributions to this game was the paper megaphone component. There was an ask to add a microphone component for the youngest player to use, so I pitched this foldable paper megaphone. (Art by Chuck Belak-Berger)
