We made a platformer inspired by Lost Vikings and Metroidvanias, where you control both Princess Bubblegum and Marceline, each one with her own mechanics. Marceline can fly and use her axe bass to destroy monsters, and PB can throw chemicals and hack into locked doors.
We used Flashpunk and Ogmo to do this, so thank you Chevy Ray and Matt Thorson! :D

PS.: The game is really short, but we had tons of fun making it, so we really hope you can have some fun with it too. :)
