Good game except...
The game was animated well, and game play was smooth with no glitches. I liked the game play system, and I think it was good with no weapons. I was really annoyed with the difficulty of the last stage. It was incomparably more difficult than the previous stages, and even with max upgrades I was unable to beat it. After about 20 or so failed attempts I gave up for fear my computer might exit my house via the window.
Excellent job though.
