It is always funny to read reviews by critics who have never made anything themselves but only good at moaning and complaining. The game is a clone, and its not a bad one, I remember when I played the original one, mechanics almost the same, this one is slightly easier. The graphics are not the most attractive but playable. I would suggest instead of repeating cubes all the time, you can make other shapes, maybe triangles, circles, and maybe make some of them move up and down for more challenge. Maybe add a petrol to the helicopter and a can of fuel, that you can pick up as a power up to continue flying, this would increase difficulty. Some sound effects simple ones could be added, as well as maybe short soundtrack of some sort on the loop. Overall its just tiny little things, when added them would make a more fun game to play. Have a go on improving it and dont let certain reviewers put you off :)
