SousaPalooza An excellent game
Being a tuba player myself (and thus a fan of Sousa marches) I really appreciated the work you put into this game. Although not all of the entrances of the enemy intruments lined up with what instruments where entering musically I really enjoyed watching it happen when it did line up. Even if some of the gameplay could be a little better (addressed below) this game is interesting enough when looking simply at the artistic side of this game. I actually found this game to be a breath of fresh air from all the other more stereotypical games.
The only way the gameplay was lacking was that everything happens way to fast. I can understand that the speed of gameplay highlights the faster more brisk tempos of Sousa's marches, but at the same time there were too many enemies shooting too often with shots that moved too fast across the screen. It was simply too much to be able to react to the enemies' shots. It also was unexciting just holding down the space bar the whole time. These two elements mostly made the game into a "move your tuba around while holding down the spacebar and hoping not to be shot by chance."
Honestly, I absolutely loved this game for how unexpected it was and how intricate the design was and how artistic it was. I would love to see more games like this. Perhaps you could even do a whole series of them using various syphonies and other well-regarded classical music...just think of all the possibilities. Anyway, thank you for this game.
