hey ! i just finished playing you're game , it was very fun !
however , the content for the game is really low , here is what you can add for the game in the futur :
-More tower
-varied enemies
-Multiple map
-a map editor ? (not really needed )
-a story for the game (If you can make one , not needed but could be cool)
-a main menu ( lunch the game , setting...
-a fullscreen mode !
i'll give the game a solid 6/10
highscore : 328 with 3897570 $
