Greenfoot Spaceinvaders_v2.0

This is my first Game.
It's based on Spaceinvaders, but with many additional Upgrades.
You can move left and right with "a" and "d".
Shoot with "w" (i suggest to hold it permanently :P)
Shoot rockets with "s".
You also have a nuke with "b" (one single time, so use it wisely)
Use a fast laser ray to clear as many enemies as you can with "v"


Have fun :)

collect upgrades and get to higher levels!

Try it out and give me feedback!
Im still working and patching on that game :)
