I dont see the point..!
We can all agree that a simple game, is a fun game because it dosent require much hard-thinking, like you would with a game like math-invaders. The layout of the game was sweet and simple.
So why make a simple game so complicated and hard?
This game relies on a large amount of LUCK,
The spaceships timelimit was roughly 3 secinds,
and many missions were extremely frustrating.
If you managed to comoplete the second level, its basically all down to trial and error, and once you have completed it, it seems very simple but unfillfulling and you remeber the 30 times you had to go back and repest the mission.
Work on the gameplay, otherwise this is not home-page material.
