A great concept; I especially love the introduction of new types of platforms along the levels. However, the actual gameplay itself is quite shaky, especially because the physics are a bit janky and unreliable. The tiniest of bumps in the road can cause a complete standstill, and the trajectories when falling or launching can be a bit haphazard.
Nonetheless, I love the design, there's some great potential here. I'd love to see what this game would be like with some more polish!
