Hey, thanks for the feedback, I really don't know why I turned off the space key for jump when i had it before haha, it's a good lesson for the future! Yeah the physics is a bit janky, it's hard to write a character controller from scratch (with a physics engine i haven't used before) in this short time that works well with moving platforms heh. Btw, for the puzzle you mention, the trick is that you have to shoot the bubble down while jumping the gap. It's a bit tricky, but the center of the bubble (smaller than the player) is the only thing that collides with walls. I wanted to make it visually clear but no time as usual. Yeah a lot of possibilities with the mechanic for sure, I feel we barely scratched the surface!
