Very cute game! I love the ball people.
I did get stuck at some parts. I think the bouncy pads weren't super easy to spot in the environment, and the rising floor texture near the end looked like lava so I didn't think I could walk on it.
Otherwise I thought the crystal mechanics were very clever, especially jumping and hanging on walls with them. And the environment design / props were very cute! Also enjoyed the morphing platforms, were those some kind of blendshape?
Overall great job team!
