Awesome game! Good level variety, and jumping the ice cube from platform to platform is surprisingly satisfying. The art is great, especially on the cover and the bar on the top, but the platforms not being textured is a bit of a drawback.
The main quality-of-life changes I'd like to see would be increasing the platforms' grab hitbox to make them easier to rotate, as well as not making the timer tick down until you've moved a platform, so you can have more time to analyze the situation.
