Okay, seriously this thread is way too small for a game this good. I actually got the game a month or two ago, after seeing it in the Hidden Gems thread, and it hasn't left my device since. It's one of those game that is simple in theory, but is a challenge to master and perfect. The controls are so easy as can be: left side for left thruster, right side for right thruster. All you have to do is get your crate to the finish area.
Now actually accomplishing that goal is far more difficult; maneuvering your platform and keeping the crate balanced is a challenge (hopefully in a satisfying to practice and improve kind of way for most) and that's not before you're weaving through tight tunnels and avoiding hazards. You need perfect timing and control to achieve the best times
I highly recommend Kona's Crate. It's a fun and challenging physics platformer with a lot of content
