A fun, polished and very HARD game, i love the menu, the theme music is so calm and beautiful, increasing the mass of the ball will make it a lot better i guess, and starting with much easier levels too. I like the first groupe of gems that you don't have to collect, only to increase your score i suggest you make all of the blue ones like that! to be precise in this game is almost impossible since the ball moves too fast! but this can reall turns out to a very beautiful game if only you change small stuff, and oh ! make it so the player respawn always in the check point :) good job tho , i enjoyed playing it.
