It looks more like a cheap mobile game.
Very bad mouse control.
Almost no balance.
The towers are quite weak and too expensive.
Your only help is a slow charging laser.
Almost everything is similar in the game tower enemies unless you get too close.
Boring repetitive levels the same.
There is no level of difficulty and they are played as if they were the last time.
I don't even know if it's worth it even with a discount.
