bad implementation - it never gives you the retry option when the ball hits an obstacle and dies; and it so often just stops your game and makes you press retry when it's going perfectly well. also, sliding behaviour not well-defined.
Nice graphics, and @MuffinStalker this indeed reminds me of the Impossible Quiz (which I never managed to beat). Make it a longer game with save points and it'll be great!
epic good game, comparable quality to continuity game and the company of myself. deserves to go onto the top puzzle games list.
would be even better if there's a "win" screen after finishing all in-game achievements!
