I found an glitch: Throw the nerd and when he hits a cannon, throw him straight up.
He won't move, not a single feet, but he will go very high. When he falls down, he will have a flaming aura, and since he's not moving, the throw will end once he hits the ground, and he'll go back walking WITH the flaming aura!
Some suggestions here:
Add a hard mode, or be able to stack various waves, by pressing the next wave button in a wave.
I also fond an insignificant critter (bug) in the game. When you click the ADVANCE WAVE buttin, if you keep clicking rapidly, the wave will never start until you stop.
Nice game.
Every game that is above average has thousands of people chanting:
"WE NEED BADGES"
"VOTE UP IF YOU WANT BADGES"
Not every game needs it! This one DOES NOT deserve it.
The only badges they implement are low for a reason people!
