The game is good, i like it
but first the health bar is more important then the look of enemy because i couldn't even see the bars and i need to use all of my money to but turrets that barely finished the first wave,
when i wanted to see the research menu and tried to go back to fight it just throw me at the main menu and i started from the zero,
To be hones the game is good when you first entered the level i get a little confused when there was texts, if you added the look's of the towers it would be better,
in short the game was good, good programming!
