The game is fun, but there is very little here that is keeping me going.
It's a little monotonous. A little variety in the shape and size of the debris, or maybe power ups or temporary abilities could help break up the monotony and keep things flowing.
For a game that emphasizes how high can you go, a little meter telling me such will also help in keeping the player's interest.
Not bad, but it needs a little more features to hold interest.
