this game is 100% impossible. the controls are WAYYYYYYYYYYYYYYYY too touchy. i got 45 death of hitting the top and bottom of the screen. if i press up it will either fly directly up to the top of the screen, or barelt move then hit the bottom 2/5 just too hard and annoying
If the game is too laggy, minimize your browser window. It will free up memory otherwise taken by the visuals. A 5min level due to lag will only take about 45s-1min.
the only way to get cash is by getting the waves in early, and this could even be by 1 second. still, the enemies started pummeling me on easy difficulty with 5 upfraded towers, one fully upgraded, and the rest leveled up. way too difficult and too exspensive for towers 2/5.
