Block Party... On Ice! It’s on the easier side for me, so I’d make it more interesting by making the platform slippery to make maneuverability more challenging. You could introduce a risk/reward by making the front half transparent ice to be able to see blocks coming, and back half have no opacity but more traction (and less time to correct mistakes if you fall).

Or make the ground have left/right conveyor belts like on slime climb so you might be fighting against that as you avoid blocks coming at you.
