It is a welcome change to see an upgraded version of one of the classics and Smashteroids doesn't disappoint at all.
Your goal is to clear out all of the asteroids on the screen and take down the passing space ships before either of them get you.
Once you have cleared a stage of all of the asteroids in Smashteroids, you will advance to the next level. The levels will keep on increasing in difficulty, but that would not stop you from still playing the game again and again.
To mover your ship around you will use the arrow keys. To shoot at your targets you just need to point the front of your ship in the right direction and press the space bar.
Enjoy playing Smashteroids and trying not to get yourself killed.
