Oh, we appreciate all these advices and troubles found by playing our game. Indeed, it's possible to finish the game without the jumping skill, but we prefered to let some plattformer details to emphasize the genre. Godot, as many says, is a good game engine for prototyping and, once you're familiarized with it, take part upon a Jam is pretty fun and confortable; we recomend this engine wherever we Jam. Thanks for the help with the feedback and let's see the Slow Ride guy! Good Luck!
