Use the mouse to control the rocket. Avoid the blocks of a shattered planet. Destroy all the aliens, you have five lives. Use the lives carefully. Also aliens don't attack you. Heal up with hearts that spawn randomly.
Well. Some of the credit goes to Minecraft for the block idea. Also thank you to literally every thing about aliens. If you see any bugs or errors in the game report them to me in the comments. Also if you have any ideas for any updates. Put them in the comments. Make any mod of this game that you want!
