the exact same game as we already had like 5 times.

not good

Could have been great.
pros: fun upgrade system, the progression of the game looks like it changes (the back ground/ enemy's)
cons: the enemy's models over lap so you can't tell if it is one or five, the animation needs a lot of work (can't tell if when they are hitting the base).

Are you recycling old games ?

A simple defense game that is fun to play.
