Thanks for you comment, front flipping was definitely a recurring subject for several days (and maybe still is) during the development, but we really wanted to push for the idea of a single-input system with a clean interface, which is why we ended with just the back flip. However, it's not off the table for future updates. Maybe we'll make it so different minecarts can do different types of tricks perhaps? Anyways, thanks for playing, we're glad you liked the game :-)
