LONG
Man, average game.
Long like hell, no level must be more than 10 min long, and thats way too much, at least in my opinion, if you fail imagine yourself playing another 20 min a level that is repetitive, same ship, the power ups appear in random order, if you got the anihilator at the end its not good, and twister beam at the begin :S. I like it at first but now im not sure im gonna give you a , too much work is need to be done. ANd Twister is way too powerfull, i think. Shorten the game. Make it not repetitive, add i dont know, big sub-bosses or the like, an optional or side mission. And instead of throwing all the power ups in every level randomly, put the next level of the weapong when you defeat the boss or at the beginning of the next level, or make it a purchasable upgrade. This could be improved.
