I can't say there was anything too bad about this. I think its main flaw was that it was just the same thing over and over. The part I found to be the weirdest was how there was really variety at ALL. I thought that I might finish the level when I had at least 1000 points, but I didn't. How do you advance in this? The music isn't bad at least.
I basically could stay in the same spot the whole time, just using the A and D keys. The alien that got out seemed to just go out on his own. I wish I had some way of telling you deliver that alien to the red cross place. The game is harmless enough. It just doesn't have much going for it.
