To my previous comment : even if i was not holding the key, it did used all the money i had on one click on an hero, seems because i used that key for something else, the game tough i was still holding it, please fix that and make the buy-in of "100" levels while HOLDING the key, please!
Add a notice that this game will lag to HELL if hardware acceleration is disabled ; it requires stage 3D http://helpx.adobe.com/x-productkb/multi/stage3d-unsupported-chipsets-drivers-flash.html
Will look into it.
