Good. The graphical style is good, and the control style is unique. A practice level would be good, and (though I haven't finished the game as of yet) a sort of sandbox or challenge mode would be really great, especially for leaderboard integration. The sounds are okay, but there is no music, which could be added. I dislike the fact you can access any level at random, but that might be due to the fact that this was developed in 30 hours. The box also seems to get caught at some points. Overall, good effort + concept, 4/5.
Good. The graphics are decent, and the music is good, but repetitive and gets boring after a while. The gameplay is good, and I love the concept, very unique, but it has poor execution. The game introduces all elements to you at once, even the options. All the bonuses are displayed, and the text is unreadable whilst playing. Make a few instruction pages, or a tutorial in the game, and then give the list of bonuses and things like that. Other than that, good, but requires more levels and a difficulty increase at the same time. 4/5 for good effort and concept.
