To be honest, BTD4 sold out before it came to kongregate. It just changed its currency to kreds, but overall this is is becoming worse and worse with kreds and the MMO's constant front page promotion
I liked the game, but seriously fix the restart button, the button to your site is broken too, and while your at it make the game over screen less surprising (I would like to know why I lost).
First off, unexplainable boy you really did a good job of posting first on a game that has 4 plays. And the game? Epic fail... create your own game maker, really. Go learn flash
Good game, took me about 7 stages to find the upgrades. Crack out on STR and REP and you're virus will be godlike. As someone else said, multiplayer would have been awesome (Release a stand alone mutliplayer version of this!)
Awesome flash racing game. The controls are fun to drift with but you still have control, and all the opponents stick in a pack so the race is more fun and your not just chasing down the guy in first. Great game 5/5
