very cool concept. Although it's not a game, it's still very interesting. I went through a phase like this when i was younger when i would just obsess and draw on grid paper.
nostalgia'd :)
the best character to front wheelie is Letter F, since his front wheel is huge. You pretty much need him for the higher wheelie achievements.
As for rear wheelie, use either elvis or the zombie, i did the 10 second rear with the zombie.
Sneaky Start: Push up the second "get set" dissapears.
To do the "doublepitstochesty" (dumb name >_>) thing, click on the award tab, and click the top left circle, then right (and hold) move your mouse to the circle one at the bottom.
thanks kaytti, i've been wondering about that ever since the first game. I used to go on youtube and watch videos of people doing it to see how much mana they had when they let the monsters go through
for the last epic, place the majority of your towers near the top right and line the trail with trenches. I was lvl 73 when i beat him.
Also, place single towers near every bend in the trail so you can move a lvl 7 purple as he makes his laps. I got 23k mana, and he only took around 5-6k mana when he went through.
i glowing framed every level but the last...and i can't beat it! >.< i mean, 146k hp? really? Even at level 73, I tried my best with trenches and makin' seven and only got it down to 20k... ;_;
