To get all of your people upgraded before even getting to level two heres what you do. As soon as you beat level one use all of it on health. Repeat level one and keep adding health. The reason for this is because you get a health bonus for how much health everyone on your team still has. So this goes to say the more health you have the more money you have.

Heres a little glitch/secret i found out. this is good for arrows. if you hold down the A button and while holding it down click to the side of the screen where its white, let go of the A button and it will still fire arrows. then just click back into the game. This works for all arrows and the mana charge thing. RATE THIS COMMENT UP TO KEEP IT ALIVE!!!
