I like the concept of reversing roles, and this is a good game overall. However I found it a little boring. At first it's near impossible to dodge bullets so for the most part I'm just waiting for the alien count to start dwindling. I also noticed that one of the original elements was missing, as my army became smaller and smaller they didn't speed up at all like the original game.
What I think should be done postmortem is to add speed increases, enhance the gun AI, and find a way to make the player more involved.

Agreed! Thanks for your feedback! Time is to blame here.

Good concept. A little slow.

Nicely executed idea, I would have liked my invaders to speed up.

Fun concept. Well done for the time frame. I echo PIXEL^3. One other thing, maybe its just my memory, but I think the original army had to cross the entire screen no matter how wide they were.

The reversed spaceinvaders was nice though i had to wait until it got diffucult. Good villainy twist!

The descending is a bit confusing. Otherwise a good concept of dodging.

Well done for getting something together in that short space of time! The movement of enemies and player certainly fit the bill but the gameplay is a bit lacking.
