The game has a lot of potential. Unfortunately, it didn't stand up to it.
The art-style and graphics are simply amazing. Music is nice. Gameplay is good. However, the game mechanics aren't so smooth. Also, instead of just scores, you can create missions/stages for players. Some storyline and medals would be good as well.
The author, without an iota of doubt, has talent. Just a little more work Speckd and you'll come up with a really great masterpiece. All the best for your future works!
