Here is my opinion about this game

Good things about this game

Really great graphics and sound effects for everything

The area looks good

The limited space is a good mechanic

Multiple enemy types instead of one type of enemy getting stronger and stronger

Things that could be fixed

Enemy's were kind of off on the path 

A selling option so that you can replace your cheap towers with bigger

Settings to turn off music and sound

Maybe add more towers and enemies that are more unique and do other things
