It’s a tough game. Persistence is the key. I haven’t run into anything yet that seemed too impossible, but I’m probably only about halfway. Which not being able to see what level you’re on or track progress is kind of lame. Also, it would be nice if there was a way to replay levels and collect diamonds that were missed. Other than that, visuals, controls, gameplay are all excellent. I really like how you immediately restart after dying too. No wait time in between. Which is good, because you die a lot.
