This is a sick joke.
Levels 40+ genuinely took me at least 15 minutes each (until I quit the game and promised myself never to touch it again).
I need a hot chocolate now.
Try juggling
It's where you make 2 paths and shut one off.
You then send all of the creeps
When they near the end, sell the tower blocking the 2nd path and block off the 1st.
They should then go round the other way.
Keep selling and blocking until you have won.
