I think the graphics were to basic and the physics unrealistic. If you wanna make this game good let your player shoot and move freely and have enemies spew money when they die. If you wanna join my team then contact me. We have enough resources to make this game good. We're looking for a good programmer.
btw. Unless you can collect two extra balls or lit a tower and get an extra ball it's a waist to go after them. ex. If you have 2 balls and fire one at an extra you'll end up with 2 and you lost the opportunity to ace it.
Really fun but one thing that got on my nerves a few times was the irregular shooting of the giant rectangle things. You had to get used to the different pattern for each one which was fun the first two or three times but got a little annoying.
