i think there should be like a box that gives you health in deathmatch when you need it so it repairs you. And for 3 tank coins you can get a repair to repair yourself to full health.
Here's a little glitch. Go to level 13, and place the drill right next to the power button, make sure it's facing towards it. Then, turn the power on. The power button should fall off the screen, but while it's in midair press the power button before it goes off screen and it'll teleport back to where it was.
i really think they should add a freeplay mode and a creator mode so you can do what ever you want to. i give the game 4/5 if they add this ill give it a 5/5. i really like freeplay and creator mode.
