This game is great. I love the concept and humor and the game is really fun. I just have a few suggestions is that the waves are too easy to defeat which makes the game to short in my opinion and secondly, I think there should be a way to customize your background, logo and shop etc. in addition to just being able to upgrade it into a premade design. Other than that the game is perfect and I would love to see an 'Upgrade Complete 2'.

63000, the number to fully upgrade the missle weapons, with 5 missles, and 5 normal guns, and 2 agility things maxed out, you can easily clear level 20/20

6, the number of fully upgraded missile weapons that it takes to clear wave 20 consistently. it is possible with 5, but you will lose waves with that

Great game, putting together the ship could get a little annoying (because it was hard to select what you wanted) but that was only a minor drawback that can be fixed in Upgrade Complete 2!
