Great, but not perfect
A wonderful, slightly fast-paced, twist on the defense genre, but spawning mechanics and other small but essential features failed at working well enough.
Terrible replay mechanics
Honestly, the concept is an amazing idea, I love any game that uses upgrading cannons as a mechanic. But the saving, level design, WAVE SELECTION, and slow turret made this otherwise brilliant idea a load of garbage. I stuck with it up until level 17, that was the final straw. I would suggest removing the 1 time stat reset and allowing the player to redistribute their stats whenever they want OR allowing them to keep some of the money they would have made when they won (say a percentage) even if they lose, and making the resets cost money. All in all 7/10 concept 1/10 for mechanics and 0/10 for level/wave selections. I would suggest you remove level 17 all together... now.
cool, but save bug!
Fun game, really hard though. And saving doesn't work (when trying to load, it doesn't find a save game)
bad game weak graphics , boring style ....
On the 4th level, at 10 seconds left, i got rushed by 10 tanks, why would you make it randomly spawn units? Good concept but it still failed.
