Did your project say "Use the tank tutorial demo to create a crappy game"? If so, you and the dozens of other idiots that did this deserve a prize. This the same school that loaded Kong down with the hundreds of "shooting gallery" clones?
Wait for a ship to spawn that takes about 4 or 5 shots to kill. Crank up the ship level while it is being fired upon. When it dies, it'll give you the coinage of whatever ship level you managed to increase to.
Hi, I'm looking for more feedback on this. Can you explain further? Some players had to zoom out to see the whole game.
